    3 Description
    The ADS8684 and ADS8688 are 4 and 8-channel, integrated data acquisition systems based on a 16-bit successive approximation (SAR) analog-to-digital
    converter (ADC), operating at a throughput of 500-kSPS. The devices feature integrated analog front- end circuitry for each input channel with overvoltage protection up to +20 V, a 4- or 8-channel multiplexer with automatic and manual scanning modes, and an on-chip, 4.096-V reference with low temperature dnift. Operating on a single 5-V analog supply, each input channel on the devices can
    support true bipolar input ranges of +10.24 V, +5.12 V, and +2.56 V, as well as unipolar input rangesof0Vto10.24Vand0Vto5.12V.Thegain of the analog front-end for all input ranges is accurately trimmed to ensure a high dc precision. 1 The
    input range selection is software-programmable and independent for each channel. The devices offer a 1-MQ constant resistive input impedance irespective of the selected input range. The ADS8684 and ADS8688 offer a simple SPI-compatible serial interface to the digital host and also support daisy-chaining of multiple devices. The digital supply operates from 1.65 V to 5.25 V, enabling direct interface to a wide range of host controllers.
