ADS8688 is an 8-channel integrated data acquisition system based on 16 bit successive approximation (SAR) mode A digital converter (ADC) can operate with a throughput of up to 500kSPS. These devices provide Integrated analog front-end circuits for each input channel (overvoltage protection up to 20V) support automatic and Manual 8-channel multiplexer with two scanning modes and low temperature drift chip 4.096V Reference voltage. When using a 5V single analog power supply, all input channels on the device can be supported Holding 10.24V, 5.12V and soil Actual bipolar input range of 2.56V and 0V to Single pole input range from 10.24V and 0V to 5.1 2V. Analog front-end within all input ranges The gains are precisely tuned to ensure high DC accuracy| The selection of input range can be done through the software

The selection of input ranges for each channel is independent of each other through programming. This device provides A constant resistive input impedance of 1 MO (regardless of the selected input range).
