These parts can operate equally well as either multiplexers or The ADG731/ADG725 are monolithic, CMOS, 32-channel/ demultiplexers and have an input signal range that extends to the dual 16-channel analog multiplexers with a serially controlled supplies. In the OFF condition, signal levels up to the supplies 3-wire interface. The ADG731 switches one of 32 inputs are blocked. All channels exhibit break-before-make switching (S1–S32) to a common output, D. The ADG725 can be config- action, preventing momentary shorting when switching channels. ured as a dual mux switching one of 16 inputs to one output, or a The ADG731 and ADG725 are serially controlled 32-channel, differential mux switching one of 16 inputs to a differential output. and dual/differential 16-channel multiplexers, respectively.
