Overview
The AD7876CR-REEL, produced by Analog Devices Inc., is a fast, complete 12-bit analog-to-digital converter (ADC). This component integrates a track-and-hold amplifier, an 8 μs successive approximation ADC, a 3 V buried Zener reference, and versatile interface logic on a single chip. It is designed to operate with a self-contained internal clock, eliminating the need for external clock timing components, although an external clock can be used if required. The AD7876CR-REEL is part of the AD7870/AD7875/AD7876 family, offering various input ranges and high accuracy specifications.
