GENERAL DESCRIPTION

The ADG725/ADG731 are monolithic CMOS 32 channel/dual 16 channel analog multiplexers with a serially controlled 3-wire interface. The ADG732 switches one of thirty-two inputs (S1-S32) to a common output, D. The ADG725 can be configured as a dual mux switching one of sixteen inputs to one output or a differential mux switching one of sixteen inputs to a differential output.
