AD7091R-2/-4/-8 Ultralow Power 12-Bit ADCs

Analog Devices Inc. AD7091R-2/AD7091R-4/AD7091R-8 Ultralow Power 12-Bit ADCs feature multichannel 12-bit, ultralow power, successive approximation analog-to-converters (ADC) available in two, four, or eight analog input channel options. The AD7091R-2/AD7091R-4/AD7091R-8 operate from a single 2.7V to 5.25V power supply and can achieve a sampling rate of 1 mega samples per second (MSPS). The AD7091R-2/ AD7091R-4/AD7091R-8 contain a wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 1.5 MHz. The AD7091R-2/AD7091R-4/AD7091R-8 also feature an on-chip conversion clock, an on-chip accurate 2.5V reference, and a high speed serial interface.
