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.

The reference is derived internally from VDD. This design allows
the widest dynamic input range to the ADC; that is, the analog
input range for the AD7091 is from 0 V to VDD.
PRODUCT HIGHLIGHTS
1. Lowest Power 12-Bit SAR ADC Available.
2. High Throughput Rate with Ultralow Power Consumption.
3. Flexible Power/Throughput Rate Management.
Average power scales with the throughput rate. Power-down
mode allows the average power consumption to be reduced
when the device is not performing a conversion.
4. Reference Derived from the Power Supply.
5. Single-Supply Operation.
