Product Summary

The AD7871JN 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 AD7871JN 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. The applications of the AD7871JN are Digital Signal Processing, High Speed Modems, Speech Recognition and Synthesis, Spectrum Analysis, DSP Servo Control.
