Overview

The AD7793BRUZ are 3-channel 24-bit, low noise, low power Sigma-Delta ADC with on-chip instrumentation amplifier and reference for high precision measurement applications. Signals of small amplitude can be interfaced directly to the ADC. With a gain setting of 64, the rms noise is 40 nV when the update rate equals 4.17 Hz. The complete analogue front ends device contains a precision low noise, low drift internal band gap reference and can accept an external differential reference. Other on-chip features include programmable excitation current sources, burnout currents and a bias voltage generator. The bias voltage generator sets the common-mode voltage of a channel to AVDD/2. ADC can be operated with either the internal clock or an external clock. The output data rate from the part is software programmable and can be varied from 4.17Hz to 470Hz.
