This circuit provides a simple, elegant interface between the ADL5373 I/Q modulator and the AD9779A high speed DAC. The ADL5373 and the AD9779A are well-matched devices because they have the same bias levels and similarly high signal-to-noise ratios (SNR). The matched bias levels of 500 mV allow for a "glueless" interface–there is no requirement for a level shifting network that would add noise and insertion loss along with extra components. The addition of the swing-limiting resistors (RSLI, RSLQ) allows the DAC swing to be scaled appropriately without loss of resolution or of the 0.5 V bias level. The high SNR of each device preserves a high SNR through the circuit.

The circuit described in this document is a high-performance, unipolar, precision DAC configuВ­ration which employs theAD5450/AD5451/AD5452/AD5453 family of precision multiplying DACs, the OP177 low-noise, high precision operational amplifier (op-amp) and the ADR01 precision 10 V reference. Because the op amp dictates the overall circuit dc performance in terms of precision, the OP177, a high precision, low noise op amp, is well matched for performance-driven applications. This circuit also uses the ADR01, which is a high accuracy, high stability, 10 V precision voltage reference. Because voltage reference temperature coefficient and long-term drift are primary considerations for applications requiring high precision conversion, this device is also an ideal candidate.

Overall performance of a transmitter, wired or wireless, is a strong function of the output power of the amplifier. If the signal is weak, bit error rate (BER) or modulation error rate (MER) will degrade due to low SNR. If the signal is too strong, distortion will cause the same issues. This circuit uses the ADL5331 VGA, the AD8319 power detector, and the AD5621 low power nanoDAC to generate output power control accurate to 12 bits. The AD8319 has very high temperature stability to compensate for any gain variation over temperature of the VGA, resulting in very accurate power control over a wide temperature range. Because the AD8319 control input VSET and the output VOUT are related to the RF input on a volts/dB scale and the AD5621 nanoDAC has a linear transfer function, the resulting output power control will be a linear-in-dB vs. DAC input code.

Digitally controlled current sources are critical functions in a variety of applications, such as power management, solenoid control, motor control, impedance measurement, sensor excitation, and pulse oximetry. Here we describe three current sources with serial interface digital control using DACs, op amps, and MOSFET transistors. The DACs selected are high resolution (14- or 16-bit), low power CMOS with standard serial interfaces. The AD5543 16-bit DAC is packaged in ultracompact (3 mm ? 4.7 mm) 8-lead MSOP and 8-lead SOIC packages. The AD5446 14-bit DAC is available in a small 10-lead MSOP package. The two DACs are both compatible with most DSP interface standards and also SPI, QSPI, and MICROWIRE. The external reference voltage input allows many output level variations, up to 10 V. The combination of parts represents industry-leading small PC board area, low cost, and high resolution. The three designs offer low risk solutions and use industry-standard parts.

The circuit in Figure 1 is a 4 mA-to-20 mA current loop transmitter for communication between a process control system and its actuator. Besides being cost effective, this circuit offers the industry’s low power solution. The 4 mA-to-20 mA current loop has been used extensively in programmable logic controllers (PLCs) and distributed control systems (DCS’s), with digital or analog inputs and outputs. Current loop interfaces are usually preferred because they offer the most cost effective approach to long distance noise immune data transmission. The combination of the low power AD8657 dual op amp, AD5641DAC, and ADR02 reference allows more power budget for higher power devices, such as microcontrollers and digital isolators. The circuit output is 0 mA to 20 mA of current, and it operates on a single supply from 8 V to 18 V. The 4 mA to 20 mA range is usually mapped to represent the input control range from the DAC or micro-controller, while the output current range of 0 mA to 4 mA is often used to diagnose fault conditions.


The 14-bit, 5 V AD5641 requires 75 μA typical supply current. The AD8657 is a rail-to-rail input/output dual op amp and is one of the lowest power amplifiers currently available in the industry (22 μA per amplifier over the full supply voltage and input common-mode range) with high operating voltage of up to 18 V. The ADR02 ultracompact precision 5 V voltage reference requires only 650 μA. Together, these three devices consume a typical supply current of 747 μA.


The circuit has a 12-pin Pmod™ digital interface (Digilent specification).

The circuit shown in Figure 1 is a single-supply, low power, window detector with programmable upper and lower limits. This type of circuit can be used to generate an alarm if a signal falls outside the preset limits and is popular in detection and monitoring applications. The AD5668-1 octal, low power, 16-bit, buffered voltage-output DAC is used to set the limits of the window. The AD5668-1 has an on-chip, 1.25 V, 5 ppm/°C reference, giving a full-scale output range of 0 V to 2.5 V. The internal reference is enabled using a software write. An SPI interface is used to communicate with the AD5668-1.

The comparator used is an ADCMP370, a general-purpose, low power comparator (20 μW typical at 5 V) with an input offset voltage of 9 mV maximum and an open-drain output.

The circuit shown in Figure 1 is a multichannel, flexible, analog output solution with only two analog components and meets most requirements for multichannel I/O cards, programmable logic controllers (PLCs), and distributed control systems (DCSs) applications. The AD5686R quad, 16-bit nanoDAC+ with rail-to-rail buffered outputs combined with four of the AD5750-2 industrial current/voltage output drivers provide all the typical output current and voltage ranges with 16-bit resolution, no missing codes, 0.05% linearity, and less than 0.1% output error.


An ultralow drift (2 ppm/°C typical), 2.5 V voltage reference with high drive capability (up to ±5 mA) is integrated in the AD5686R and provides the reference voltage for both the AD5686R and the AD5750-2. This guarantees low noise, high accuracy, and low temperature drift for the circuit.


The ADuM1301 and ADuM5400 provide 2500 V rms isolation both on power, and all the necessary signals between the analog signal chain and the host controller.


For multichannel I/O card applications that need more than 4 channels, several AD5686Rs can be connected in a daisy chain, and no additional external digital I/O circuits are required. This minimizes the cost, especially for high channel count isolated applications.


The circuit also contains key features for industrial applications, such as on-chip output fault detection, packet error checking (PEC) by the CRC, flexible power-up options, and ESD protection (4 kV for the AD5686R, human body model and 3 kV for the AD5750-2, human body model), making it an ideal choice for robust industrial control systems. No external precision resistors or calibration routines are needed to maintain consistent performance in mass production, thereby making it ideal for PLC or DCS modules.

The circuit shown in Figure 1 is a complete smart industrial, loop powered field instrument with 4 mA to 20 mA analog output and a highway addressable remote transducer (HART®) interface. HART is a digital 2-way communication in which a 1 mA peakto- peak frequency-shift-keyed (FSK) signal is modulated on top of the standard 4 mA to 20 mA analog current signal. This allows features such as remote calibration, fault interrogation, and transmission of process variables, which are necessary in applications such as temperature and pressure control.


This circuit has been compliance tested, verified, and registered by the HART Communication Foundation (HCF). This successful registration provides circuit designers with a high level of confidence using one or all of the components in the circuit.


The circuit uses the ADuCM360, an ultralow power, precision analog microcontroller, the AD5421, a 16-bit, 4 mA to 20 mA, loop powered digital-to-analog converter (DAC), and the AD5700, the industry’s lowest power and smallest footprint HARTcompliant IC modem.

The circuit shown in Figure 1 uses the AD5700, the industry’s lowest power and smallest footprint HART1-compliant IC modem and the AD5420, a 16-bit current-output DAC, to form a complete HART-compatible 4 mA to 20 mA solution.


For additional space savings, the AD5700-1 offers a 0.5% precision internal oscillator.



Figure 1. AD5420 HART-Enabled Circuit Simplified Schematic

This circuit adheres to the HART physical layer specifications as defined by the HART Communication Foundation, for example, the analog rate of change and noise during silence specifications.

For many years, 4 mA to 20 mA communication has been used in process control instrumentation. This communication method is reliable and robust, and offers high immunity to environmental interference over long communication distances. A limitation, however, is that only 1-way communication of one process variable at a time is possible.


The development of the highway addressable remote transducer (HART) standard provided highly capable 2-way digital communication, simultaneously with the 4 mA to 20 mA analog signaling used by traditional instrumentation equipment. This allows for features such as remote calibration, fault interrogation, and transmission of additional process variables. Put simply, HART is a digital two-way communication in which a 1 mA peak-to-peak frequency-shift-keyed (FSK) signal is modulated on top of the 4 mA to 20 mA analog current signal.

The circuit shown in Figure 1 is a complete solution for the conversion of HDMI/DVI to VGA (HDMI2VGA) with an analog audio output. It uses the low power ADV7611 high-definition multimedia interface (HDMI) receiver capable of receiving video streams up to 165 MHz. The circuit is powered from a USB cable and works for resolutions up to 1600 ? 1200 at 60 Hz. The circuit uses extended display identification data (EDID) content to ensure that the video stream from the HDMI/digital visual interface (DVI) source is at the highest possible resolution supported by the HDMI source, converter, and video graphics adapter (VGA) display. Figure 1. HDMI-to-VGA (HDMI2VGA) Converter Block Diagram (Simplified Schematic: All Connections Not Shown) The HDMI receiver can also be used for video adjustments, such as brightness or contrast, and the audio codec can be used to set the volume of the audio output. There are numerous benefits of this circuit. The highly integrated video receiver allows video adjustments without the need for additional field-programmable gate arrays (FPGAs). A simple I2C write can adjust brightness, contrast, or change the audio volume. Built-in EDID memory reduces the count of the parts and the real estate. Step-down switching regulators allow the circuit to be powered from a USB port. By using industry-standard interchip connections, direct connections can be made between the receiver, codec, and video digital-to-analog converter (DAC). The circuit was built on a 2-layer printed circuit board (PCB), and it works up to UXGA resolutions (1600 ? 1200 at 60 Hz).

При ошибке измерения температуры менее чем 0,017 °C в диапазоне температур -200…+850°C, сверхнизким потреблением 1,4 мА (включая ток через резисторный датчик температуры) и соответствие IEC61000, этот дизайн значительно уменьшает время проектирования и разработки высокоточных систем передачи температуры. Он также адресует системный уровень калибровки смещения и усиления, которые могут быть использованы для улучшения точности АЦП и ЦАП, а также осуществлять линейную интерполяцию для адресации нелинейного элемента (резистивного термодетектора).
