AD7091R Analog-to-Digital Converter

1 MSPS, ultra-low power, 12-bit ADC from Analog Devices with on-chip reference

Image of ADI's AD7091R Analog-to-Digital ConverterADI's AD7091R is a 12-bit successive approximation analog-to-digital converter (ADC) that offers ultra-low power consumption (typically 349 µA at 3 V and 1 MSPS) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK). The AD7091R uses advanced design and process techniques to achieve this very low power dissipation at high throughput rates. The part also features an accurate on-chip 2.5 V reference.

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 and high speed serial interface. The conversion process and data acquisition are controlled using a CONVST signal and an internal oscillator. The AD7091 is ideal for low power consumption applications such as battery systems. Handheld meters and mobile communications.
