Applications
* The AD7792/AD7793 contains a low noise 16/24-bit ∑-∆ 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
