GENERAL DESCRIPTION
The AD7871 and AD7872 are fast, complete, 14-bit analog-to-
digital converters. They consist of a track/hold amplifier,
successive-approximation ADC, 3 V 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.
The AD7871 offers a choice of three data output formats: a sin-
gle, parallel, 14-bit word; two 8-bit bytes or a 14-bit serial data
stream. The AD7872 is a serial output device only. The two
parts are capable of interfacing to all modern microprocessors
and digital signal processors.
The AD7871 and AD7872 operate from
±5 V power supplies,
accept bipolar input signals of
±3 V and can convert full power
signals up to 41.5 kHz.
In addition to the traditional dc accuracy specifications, the
AD7871 and AD7872 are also fully specified for dynamic perfor-
mance parameters including distortion and signal-to-noise ratio.
Both devices are fabricated in Analog Devices’ LC
2MOS mixed
technology process. The AD7871 is available in 28-pin plastic DIP
and PLCC packages. The AD7872 is available in a 16-pin plastic
DIP, hermetic DIP and 16-lead SOIC packages.
