View Datasheet Manufacturer Site View Pricing & Stock

The AD7770 is an 8-channel, simultaneous sampling ADC. Eightfull sigma-delta (Σ-Δ) ADCs are on chip. The AD7770 providesa low input current to allow direct sensor connection. Each inputchannel has a programmable gain stage allowing gains of 1, 2, 4,and 8 to map lower amplitude sensor outputs into the full-scaleADC input range, maximizing the dynamic range of the signalchain. The AD7770 accepts a VREF voltage from 1 V up to 3.6 V.The analog inputs accept unipolar (0 V to VREF) or true bipolar(±VREF/2) analog input signals with 3.3 V or ±1.65 V analogsupply voltages, respectively for PGAGAIN = 1. The analog inputscan be configured to accept true differential, pseudo differential,or single-ended signals to match different sensor outputconfigurations.Each channel contains a PGA, an ADC modulator and asinc3, low latency digital filter. An SRC is provided to allow fineresolution control over the AD7770 ODR. This control can beused in
