概要
Description
The AD7091R-8BRUZ is an 8-bit, low-power, successive approximation ADC (analog-to-digital converter) from Analog Devices. It features:
- 8-bit resolution with a 1 MSPS (mega-sample per second) conversion rate.
- Single-channel input with an internal reference (2.5V).
- Low power consumption (1.65 mW at 1 MSPS, 0.12 mW in shutdown).
- SPI-compatible serial interface for easy microcontroller integration.
- Wide supply range (2.7V to 5.25V), suitable for battery-powered applications.
- Small 10-lead MSOP package, ideal for space-constrained designs.
Common applications include portable instrumentation, battery monitoring, and industrial control systems. Its low power and compact size make it ideal for embedded systems requiring efficient analog-to-digital conversion.
