GENERAL DESCRIPTION
The AD7091 is a 12-bit successive approximation register analog-to-digital converter (SAR ADC) that offers ultralow power consumption (typically 367 µA at 3 V and 1 MSPS) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK). The AD7091 operates from a single 2.09 V to 5.25 V power supply. The AD7091 also features an on-chip conversion clock and a high speed serial interface.
The conversion process and data acquisition are controlled using a CONVST signal and an internal oscillator. The AD7091 has a serial interface that allows data to be read after the conversion while achieving a 1 MSPS throughput rate. The AD7091 uses advanced design and process techniques to achieve very low power dissipation at high throughput rates.
