Description
- Product Details
- 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.
- **Applications**
- Battery-powered systems
- Handheld meters
- Medical instruments
- Mobile communications
- Instrumentation and control systems
- Data acquisition systems
- Optical sensors
- Diagnostic/monitoring functions
- Energy harvesting
