The ADG1406 and ADG1407 are monolithic iCMOS analog multiplexers comprising 16 single channels and eight differential channels, respectively. The ADG1406 switches one of 16 inputs to a common output, as determined by the 4-bit binary address lines (A0, A1, A2, and A3). The ADG1407 switches one of eight differential inputs to a common differential output, as determined by the 3-bit binary address lines (A0, A1, and A2). An EN input on both devices enables or disables the device. When disabled, all channels switch off. When on, each channel conducts equally well in both directions and has an input signal range that extends to the supplies.
