The AD7091R is a 12-bit successive approximation analog-to-digital converter (ADC) that offers ultralow power consumption (typically 349 µA at 3 V 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
Product Highlights
- Lowest Power 12-Bit SAR ADC Available.
- On-Chip, Accurate 2.5 V Reference.
- High Throughput Rate with Ultralow Power Consumption.
- 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.
- Single Supply Operation with VDRIVE Function. The AD7091R operates from a single 2.7 V to 5.25 V supply. The VDRIVE function allows the serial interface to connect directly to 1.8 V to 3.3 V processors.
Applications
- Battery-powered systems
– Handheld meters
– Medical instruments
– Mobile communications - Instrumentation and control systems
- Data acquisition systems
- Optical sensors
- Diagnostic/monitoring functions
- Energy harvesting
