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
- Lowest power 12-bit SAR ADC available.
- 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. - Reference Derived from the Power Supply.
- Single Supply Operation.
APPLICATIONS
- Battery-powered systems
Handheld meters
Medical instruments
Mobile communications - Instrumentation and control systems
- Data acquisition systems
- Optical sensors
- Diagnostic/monitoring functions
- Energy harvesting
