The Digilent 4 Channel 12-bit Analog to Digital Converter PmodAD2 is an analog to digital converter module with up to 4 channels at 12-bit resolution powered by the Analog Devices AD7991. It uses an 8-pin connector that allows communication via I2C. The PmodAD2 also has a 6-pin connector that allows up to 4 analog inputs or up to 3 analog inputs and a voltage reference. Device configuration is performed by writing to the configuration register within the device. This allows the user to choose which channels are to be converting data, whether or not there is an external reference voltage, and whether or not there is bit trial or sample delay.
