AD7785 - 20-Bit ADC
The AD7785 is a low power, low noise, complete analog front end for high precision measurement applications.
The AD7785 contains a low noise 20-bit ∑-Δ ADC with three differential analog inputs.
The on-chip, low noise instrumentation amplifier means that signals of small amplitude can be interfaced
