PmodAD4
The Digilent Pmod-AD4 is a 16-bit, successive approximation, analog-to-digital converter (ADC) that
operates from a single power supply, VDD.It contains a low power, high speed, 16-bit sampling ADC
and a versatile serial interface port. On the CNV rising edge, it samples an analog input IN+ between
0V to REF with respect to ground sense IN-. The reference voltage, REF, is applied externally and can
be set independent of the supply voltage, VDD. Its power scales linearely with throughput.
PmodAD6
The Digilent Pmod-AD6 is powered by the Analog Devices AD7091R, a a 12-bit successive
approximation analog-to-digital converter (ADC) that offers ultralow power consumption (typically
349 µA at 3 V and 1 MSPS) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK).
