AD7798 Datasheet (Analog Devices) - 3-Channel Low Noise Low Power ADC

AD7798, 3-Channel Low Noise Low Power ADC

The AD7798/AD7799 are low power, low noise, complete analog front ends for high precision measurement applications.

The AD7798/AD7799 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
