The MAX11600/MAX11601 provide 4 4.096V (MAX11600/MAX11602/MAX11604) analog input channels each, the MAX11602/MAX11603 External Reference: 1V to V DD provide 8 analog input channels each while the Internal Clock MAX11604/MAX11605 provide 12 analog input channels. The analog inputs are software configurable for unipolar or 4-Channel Single-Ended or 2-Channel Pseudo- bipolar and single-ended or pseudo-differential operation.
