The PmodAD5 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.
