Overview

The ADS1235 evaluation module (EVM) is a platform for evaluating the ADS1235 analog-to-digital converter (ADC). ADS1235 is a low-drift, 24-bit, 7200-SPS, 6-channel delta-sigma (ΔΣ) ADC with an integrated PGA for low-noise bridge measurements. This sensor-ready ADC provides a high-accuracy, one-chip measurement solution for the most-demanding test and measurement instrumentation, including weigh scales, strain-gauge sensors, and high-resolution pressure measurements.

The ADS1235EVM and Delta-Sigma ADC EvaluaTIon Software (DELTASIGMAEVAL-GUI) are provided to reduce prototype development time and get products to market faster.

Features
  • Includes all required support circuitry for ADS1235
  • Delta-Sigma ADC EvaluaTIon Software (DELTASIGMAEVAL-GUI) enables quick configuration and analysis
