GENERAL DESCRIPTION
The AD7193 is a low noise, plete 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 interface directly to the ADC.
Simultaneous 50 Hz/60 Hz rejection
The device can be configured to have four differential inputs or
4 general-purpose digital outputs eight pseudo...
