Texas Instruments Evaluation Module Kit
Texas Instruments’ ADS125H02EVM is designed to demonstrate the space-saving and high-accuracy ADS125H02 ADC. The ADS125H02 is a ±20V Delta-Sigma ADC with a low-noise programmable gain amplifier, internal reference, clock oscillator, and out-of-range monitoring.
This level of integration simplifies layout and reduces board area by up to 50%, compared to a more discrete design. A TI processor is used to communicate with the ADC over SPI and the host PC over USB.
Onboard regulators and LDOs are used to derive analog, digital, and ±15V rails from USB power. The high-voltage can also be supplied externally.
Designers can use the ADS125H02EVM with TI’s Delta-Sigma ADC EvaluaTIon Software to easily acquire data and manipulate registers to quickly evaluate the ADS125H02 ADC.
