The ADS127L11EVM is a platform for evaluating the performance of the ADS127L11, which is a 24-bit, high-speed, wide-bandwidth ΔΣ ADC. The evaluation kit includes the ADS127L11EVM board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over the USB for data capture and analysis. The ADS127L11EVM board includes the ADS127L11 ADC and all the peripheral analog circuits and components required to extract optimum performance from the ADC. The PHI board primarily serves three functions:
