Overview
The AD7870JPZ-REEL, produced by Analog Devices Inc., is a complete 12-bit analog-to-digital converter (ADC) designed for high-performance applications. This component integrates a track-and-hold amplifier, an 8 μs successive approximation ADC, a 3 V buried Zener reference, and versatile interface logic. It features a self-contained internal clock, eliminating the need for external clock timing components, although an external clock can be used if required. The AD7870JPZ-REEL operates from ±5 V power supplies and is available in a 28-pin plastic leaded chip carrier (PLCC) package.
