AD7871JNZ Datasheet PDF - ADI

●The AD7871JNZ is a fast, complete 14-bit Analog-to-digital Converter (ADC) consists of a track-and-hold amplifier, successive approximation ADC, 3V buried Zener reference and versatile interface logic. The ADC 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. It offers a choice of three data output formats - a single, parallel 14-bit word, two 8-bit bytes or a 14-bit serial data stream. The converter is a serial output device only. The two parts are capable of interfacing to all modern microprocessors and digital signal processors. In addition to the traditional dc accuracy specifications, the converter is also fully specified for dynamic performance parameters including distortion and signal-to-noise ratio.
