ADS1282EVM-PDK Evaluation Module

Description

The ADS1282EVM is a platform for evaluating the performance of the ADS1282, a high performance, 2-channel, 31-bit, delta-sigma ADC. The ADS1282 board includes the ADS1282 and all the peripheral analog circuits and components required to extract optimum performance from the ADC. The evaluation kit includes the ADS1282EVM board and the precision host interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC over Universal Serial Bus (USB) for data capture, configuration, and analysis.

Get Started

  1. Order ADS1282EVM-PDK from ti.com
  2. Download and install the ADS1282EVM-PDK-GUI software
  3. Connect the ADS1282EVM to the computer with the included USB cable
  4. Launch the ADS1282EVM GUI from the start menu
  5. Refer to the ADS1282 data sheet for IC details
  6. Visit the E2E forums for support and questions
