GENERAL DESCRIPTION

The AD7091R-2/AD7091R-4/AD7091R-8 family is a multichannel 12-bit, ultralow power, successive approximation analog-to-digital converter (ADC) that is available in two, four, or eight analog input channel options. The AD7091R-2/AD7091R-4/AD7091R-8 operate from a single 2.7 V to 5.25 V power supply and are capable of achieving a sampling rate of 1 MSPS.
