ADI AD7091RBCPZ-RL7

The AD7091R is a 12-bit successive approximation analog-to-digital converter (ADC) that offers ultralow power consumption (typically 349 μA at 3V and 1 MSPS) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK). Operating from a single 2.7 V to 5.25 V power supply, the part contains a wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 7 MHz. The AD7091R also features an on-chip conversion clock, accurate reference, and high speed serial interface. The conversion process and data acquisition are controlled using a CONVST signal and an internal oscillator. The AD7091R has a serial interface that allows data to be read after the conversion while achieving a 1 MSPS throughput rate. The AD7091R uses advanced design and process techniques to achieve very low power dissipation at high throughput rates. An on-chip, accurate 2.5 V reference is available.
