The ADG604 is a CMOS analog multiplexer, comprising of four single channels. It operates from a dual supply of ±2.7 V to ±5.5 V, or from a single supply of +2.7 V to +5.5 V. The ADG604 switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines, A0, A1 and EN. A Logic "0" on the EN pin disables the device.
