1 ADS1258EVM Overview

The ADS1258EVM is a platform for evaluating the performance of the ADS1258, a 24-bit, 125-kSPS, 16-channel (multiplexed), ΔΣ ADC. The evaluation kit includes the ADS1258EVM and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over USB for data capture and analysis. The ADS1258EVM includes the ADS1258 ADC as well as the high-performance peripheral analog circuits necessary to extract the best performance from the ADC. The PHI board primarily serves three functions:

  • Provides a communication interface from the EVM to the computer through a USB port
  • Provides the digital input and output signals necessary to communicate with the ADS1258
  • Supplies power to all active circuitry on the ADS1258EVM board
