Overview

The ADS122U04 evaluation module (EVM) is a platform for evaluation of the ADS122U04 analog-to-digital converter (ADC). The ADS122U04 is a 24-bit, 2-kSPS, 4-channel, low-power delta-sigma ADC with a UART interface for sensor measurement and process control applications. The ADS122U04 also includes an integrated oscillator, reference, and PGA enabling precision measurement of a wide range of input signals. Use the ADS122U04EVM and Delta-Sigma ADC EvaluaTIon Software (DELTASIGMAEVAL-GUI) to reduce prototype development time and get products to market faster.

  • Includes all required support circuitry for ADS122U04
  • Delta-Sigma ADC EvaluaTIon Software (DELTASIGMAEVAL-GUI) enables quick configuration and analysis
  • Configurable inputs, references, and supplies
  • Easily accessible signals via test points and headers

  • ADS122U04 EVM
  • USB micro-B plug to USB-A plug cable
