Product Summary

The AD7793BRUZ is a low power, complete analog front end for low frequency measurement applications. The AD7793BRUZ contains a low noise 16/24-bit ∑-Δ ADC with three differential analog inputs. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. With a gain setting of 64, the rms noise is 80 nV when the update rate equals 16.6 Hz.
