Описание:
Differential Headphone amplifiers require positive and negative voltages. In this reference design, both voltages are generated from a single input voltage with an all integrated split-rail converter. It only requires one inductor and a minimal amount of external components to achieve a high efficiency power supply that keeps the distortion of the system very low. End users benefit from High Fidelity audio performances with longer playback time in their mobile application.

Описание:
The TIDA-01051 reference design is used to demonstrate optimized channel density, integration, power consumption, clock distribution and signal chain performance of very high channel count data acquisition (DAQ) systems such as those used in automatic test equipment (ATE). Using serializers, such as TI’s DS90C383B, to combine many simultaneously sampling ADC outputs into several LVDS lines dramatically reduces the number of pins the host FPGA must process. As a result, a single FPGA can process a significantly increased number of DAQ channels and board routing complexity is greatly reduced.

The TIDA-01053 is an ADC driver reference design to optimize the THD, noise and the full system SNR for the high dynamic range instrumentation. The high capacitive nature of the ADC input presents some unique challenges for driver design and part selection process to ensure stability, low noise, high current drive capability and low harmonic distortion performance at the same time. This reference design aims to highlight performance benefits to using either a fully differential amplifier or two single ended amplifiers when driving an ADC.

The TIDA-01346 design uses two LMX2594 synthesizers in combination to produce lower noise than is possible with just one. By combining the output of two synthesizers that are in phase, a theoretical 3 dB phase noise benefit is possible due to the output power being 6 dB higher while the noise power is only 3 dB higher. The LMX2594 is an ideal synthesizer for this application as it has a SYNC feature that allows it to have deterministic and repeatable phase as well as a programmable phase that can be used to correct for any phase error due to trace mismatches or any other factors.

The TIDA-01410 reference design uses two LMX2594 synthesizers to produce two outputs that are both coherent and adjustable in phase. Phase coherent outputs are useful for interleaving data converters and also for beam steering applications. This reference design has identical routing for both synthesizers so that it is easy to measure the phase between them.

This circuit performs the function of producing a ±10V voltage output where both a high level of accuracy and a fast update rate are desired. This is achieved by combining the fast settling time and precision of a 16-bit unbuffered R-2R DAC (DAC8832) and the low input offset voltage and fast slew rate of two output amplifier stages (OPA2192). The circuit provides an analog output voltage useful for precisely tuning feedback circuits as well as driving off-board components.
