General Description

The AD7192 is a low noise, complete analog front end for high precision measurement applications.

It contains a low noise, 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC).

The on-chip low noise gain stage means that signals of small amplitude can be interfaced directly to the ADC.
