ADG725:  Differential 16-Channel, Serially Controlled 3.5 Ω 1.8 V to 5.5 V, ±2.5 V, Analog Multiplexer

Product Details


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.
