Product Summary
The AD7872JRZ is a fast, complete, 14-bit analog-to-digital converter. It consists of a track/hold amplifier,successive-approximation ADC, 3 V buried Zener reference and versatile interface logic. The AD7872JRZ features a self-contained, laser trimmed internal clock, so no external clock timing components are required. The on-chip clock may be overridden to synchronize ADC operation to the digital system for minimum noise.
