This user's guide describes the characteristics, operation, and use of the AMC131M03EVM-PDK. This evaluation module (EVM) is an evaluation platform for the AMC131M03, which is a 3-channel, simultaneously-sampling, 24-bit, reinforced isolated delta-sigma (ΔΣ) analog-to-digital converter (ADC) with integrated DC/DC converter and serial peripheral interface (SPI) interface. The AMC131M03 offers wide dynamic range, low power, and specific features for energy measurement, making the device an excellent fit for energy metering, power quality, protection relay, and circuit breaker applications.
The AMC131M03EVM eases the evaluation of the device with hardware, software, and computer connectivity through the universal serial bus (USB) interface. This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of materials. Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the AMC131M03EVM.

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:
The AMC131M03 evaluation module kit includes the following features:
