EVAL-AD7124-8-PMDZ User Guide

The EVAL-AD7124-8-PMDZ evaluation board is a minimalist 8-channel, low noise, low power, 24-bit, sigma-delta ADC with PGA and reference, SPI Pmod board for the AD7124-8. This module is designed as a low-cost alternative to the fully-featured EVAL-AD7124-8 evaluation board and has no extra signal conditioning for the ADC.

All pins of the AD7124-8 are exposed, which makes the EVAL-AD7124-8-PMDZ very flexible and easy to use.
