AD7712 - Signal Conditioning ADC

Description

The AD7712 is a complete analog front end for low frequency measurement applications.

The device has two analog input channels and accepts either low level signals directly from a transducer or high level (± 4 ϫ VREF) signals, and outputs a serial digital word.

Features

  • Charge Balancing ADC 24 Bits No Missing Codes ؎0.0015% Nonlinearity High Level and Low Level Analog Input Channels Programmable Gain for Both Inputs Gains from 1 to 128 Differential Input for Low Level Channel Low-Pass Filter with Programmable Filter Cutoffs Ability to Read/Write Calibration Coefficients Bidirectional Microcontroller Serial Interface Internal/External Reference Option Single- or Dual-Supply Operation Low Power (25 mW typ) with Power-Down Mode (100 ␮W typ).
