Overview
The AD7823YR is a high-speed, low-power 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component operates from a single supply voltage ranging from 2.7 V to 5.5 V and is fully specified over a temperature range of –40°C to +125°C. It features a successive approximation ADC with a typical conversion time of 4 µs and inherent track-and-hold functionality. The AD7823YR is designed for microcontroller compatibility with a high-speed serial interface and supports automatic power-down mode to reduce power consumption at lower throughput rates.
