Overview
The AD7866ARUZ-REEL, produced by Analog Devices Inc., is a dual, simultaneous sampling, 12-bit analog-to-digital converter (ADC) designed for high-speed and low-power applications. This device operates from a single 2.7 V to 5.25 V power supply and features a throughput rate of up to 1 MSPS. It includes a 4-channel analog input multiplexer, track-and-hold amplifiers, and two successive approximation ADCs, making it ideal for applications requiring fast and accurate data acquisition.
