CMOS, Complete 14-Bit, Sampling ADC with Three Data Output Formats
The AD7871 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 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 performance parameters including distortion and signal-to-noise ratio.
Both devices are fabricated in Analog Devices’ LC2 MOS 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.
