AD7091R-8BCPZ-RL7

AD7091R-8 is a multichannel 12bit, ultralow power, successive approximation analogue-to-digital converter (ADC). It operates from a single 2.7V to 5.25V power supply and are capable of achieving a sampling rate of 1MSPS. It offers upto eight single-ended analogue input channels with a channel sequencer that allows a pre-programmed selection of channels to be converted sequentially. It also features an on-chip conversion clock, an on-chip accurate 2.5 V reference, and a high speed serial interface. It has a serial port interface (SPI) that allows data to be read after the conversion while achieving a 1MSPS throughput rate. The conversion process and data acquisition are controlled using the CONVST pin. It is used in applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, optical sensors, diagnostic/monitoring functions.
