Story

This project shows how to use the Digilent Pmod AD5 and Arduino Uno. This project was designed to display the result of the A/D conversion of the AIN1 channel on the serial monitor.

The Pmod AD5 is an analog-to-digital converter that utilizes a fourth-order sigma-delta modulator, a programmable gain array, and on-chip digital filtering, all powered by the Analog Devices AD7193. With 24 bits of resolution on up to 8 different analog input channels, users may read the highly accurate voltage measurements with an RMS noise as low as 11 nV through SPI.
