The Maxim Integrated DG408DY+T is a single 8:1 multiplexer/demultiplexer built for routing analog or digital signals in data-acquisition, instrumentation, and industrial-control boards. It switches one of eight inputs to a common output, or the reverse in demux mode, with a maximum on-resistance of 100 ohms and channel-to-channel matching of 1.5 ohms — tight enough to keep gain errors consistent across channels in a multiplexed ADC front-end.
