... CMOS analog multiplex- ers/switches configured as an 8-channel multiplexer (MAX4781), two 4-channel multiplexers (MAX4782), and three single-pole/double-throw (SPDT) switches (MAX4783). These devices operate with a +1.6V to +3.6V single supply. When powered from a +3V supply, MAX4781/ MAX4782/MAX4783 feature a 0.7Ω on-resistance (R ), with 0.3Ω R matching between channels, and ON ON 0.1Ω ...
