The AD7779 is an 8-channel, simultaneous sampling ADC.There are eight full Σ-Δ ADCs on chip. The AD7779 providesan ultralow input current to allow direct sensor connection. Eachinput channel has a programmable gain stage allowing gains of1, 2, 4, and 8 to map lower amplitude sensor outputs into thefull-scale ADC input range, maximizing the dynamic range ofthe signal chain. The AD7779 accepts VREF from 1 V up to 3.6 V.The analog inputs accept unipolar (0 V to VREF/GAIN) or truebipolar (±VREF/GAIN/2 V) analog input signals with 3.3 V or±1.65 V analog supply voltages. The analog inputs can beconfigured to accept true differential, pseudo differential, or singleendedsignals to match different sensor output configurations.Each channel contains an ADC modulator and a sinc3, lowlatency digital filter. An SRC is provided to allow fine resolutioncontrol over the AD7779 ODR. This control can be used in
