The TIDA-00738 TI design demonstrates a unique approach for extending the current measurement range using a single shunt and voltage measurement using AMC1304Mx5 Isolated Delta-Sigma (ΔΣ) modulator. With careful selection of a low value shunt resistor that minimizes power dissipation, a front end amplifier with low noise and by introducing two gain paths, both upper and lower current limit is extended. Accuracy of < ±0.5 % for both current and voltage measurement is achieved by interfacing the modulator output to AM437x host processor which performs the Sinc3 filtering.

The TIDA-00777 TI Design shows an active integrator design that covers wide input current range for Rogowski Coil with excellent accuracy, linearity, stability and repeatability. The integrator uses a precision amplifier with very low offset and temperature drift. Two configurations of the integrator are shown; one for precision measurement with less than 3O phase error and the other for fast response time (<15ms RC). While the output signal is bipolar, optional level shifting stage can be used when unipolar output is required.
Возможности:

Active integrator design using low offset and close to zero drift amplifier (OPA2188) Integrator output compatible with unipolar or bipolar ADC input range (Ex: ADS131A04 with 0-5V or ±2.5V input) Integrator has been tested for accuracy at 50/60Hz, repeatability and temperature stability over 25°C ± 35°C The integrator operates from a single 5V DC input with positive and negative voltages for bipolar operation generated on board.

The TIDA-00809 TI design showcases a cost optimized architecture that improves resolution of a binary input module. A microcontroller unit (MCU) is shared between two input channels (group isolation) to minimize the cost per channel. Wide input range is covered using an amplifier with gain and a MCU integrated 10-bit analog-to-digital converter (ADC) to measure with in ±3% accuracy. This architecture eliminates the need for multiple hardware versions based on input voltage range as is the case with an opto-coupler based topology. A digital isolator is used to communicate the ADC code or the root-mean-square estimate of the input to the host processor. The design is tested for ESD, EFT and Surge as per IEC61000-4 Level 4.

The TIDA-00810 reference design accurately measures analog inputs performance and includes chip diagnostics to help identify power systems failures early by using a highly accuracy AC voltage and current measurement analog front end (AFE) and a four-channel, 24-bit simultaneously-sampling differential input Delta-Sigma ADC for measurement over wide dynamic range.
