1 Introduction

The AMC131M03EVM-PDK is a platform for evaluating the performance of the AMC131M03, which is a 3-channel, simultaneously-sampling, 24-bit, reinforced isolated ΔΣ ADC with integrated DC/DC converter. The evaluation kit includes the AMC131M03EVM 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 AMC131M03EVM board includes the AMC131M03 ADC and all the peripheral analog circuits and components required to extract optimum 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 AMC131M03
  • Supplies power to all active circuitry on the AMC131M03EVM board
