AD7872 - Complete 14-Bit Sampling ADCs

Download the AD7872 datasheet PDF. This datasheet also covers the AD7871 variant, as both devices belong to the same complete 14-bit sampling adcs family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD7871/AD7872 are fast, complete, 14-bit analog-todigital converters (ADC).

They consist of a track-and-hold amplifier, successive approximation ADC, 3 V buried Zener reference, and versatile interface logic.

Key Features

  • Complete monolithic 14-bit ADC Twos complement coding Parallel, byte, and serial digital interface 80 dB SNR at 10 kHz input frequency 57 ns data access time Low power: 50 mW typ 83 kSPS throughput rate.
