Description

General part information

AD7719 Series

AD7719 is a low voltage, low power, Factory-Calibrated 16-/24bit dual Ʃ -Δ ADC. The AD7719 is a complete analog front end for low frequency measurement applications. It contains two high resolution Σ-∆ ADCs, switchable matched excitation current sources, low-side power switches, digital I/O port, and temperature sensor. The 24bit main channel with PGA accepts fully differential, unipolar and bipolar input signal ranges from 1.024 × REFIN1/128 to 1.024 × REFIN1. Signals can be converted directly from a transducer without the need for signal conditioning. The 16bit auxiliary channel has an input signal range of REFIN2 or REFIN2/2. Suitable for use in sensor measurement, temperature measurement, pressure measurement, weigh scales, portable instrumentation and 4 to 20mA transmitters.
