Overview
The AD7091R-4BRUZ-RL7, produced by Analog Devices Inc., is a 4-channel, 12-bit, ultralow power, successive approximation analog-to-digital converter (ADC). This component is part of the AD7091R family, which includes options for two, four, or eight analog input channels. The AD7091R-4 operates from a single 2.7 V to 5.25 V power supply and is capable of achieving a sampling rate of 1 MSPS. It features an on-chip conversion clock, an on-chip accurate 2.5 V reference, and a high-speed serial interface (SPI) for data readout.
