Description

The AD7813YR is a 10-bit, successive-approximation analog-to-digital converter (ADC) from Analog Devices. It operates with a single 2.7V to 5.25V supply, making it suitable for low-power applications. Key features include:
- 10-bit resolution with ±1 LSB accuracy.
- Fast conversion time (2.35 µs) and a 1.5 µs wake-up time from shutdown.
- On-chip track-and-hold and internal clock, eliminating external components.
- Low power consumption (1.5 mW at 5V, 0.65 mW at 3V).
- SPI-compatible serial interface for easy microcontroller integration.
- Temperature sensor with ±2°C accuracy (optional).
Available in an 8-lead SOIC package, the AD7813YR is ideal for portable, battery-powered systems, and temperature-sensing applications. Its compact design and efficient performance make it a versatile choice for embedded systems.
