Overview
The AD7866BRUZ is a high-speed, dual 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for simultaneous sampling of two channels, making it suitable for multi-channel applications. It operates from a single 2.7 V to 5.25 V power supply and features throughput rates up to 1 Mega samples per second (1 MSPS). The AD7866BRUZ is particularly effective in rapid data acquisition systems due to its low power dissipation and high throughput rates.
