General Description

The MAX4781/MAX4782/MAX4783 are high-speed, low-voltage, low on-resistance, CMOS analog multiplexers/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 (RON), with 0.3Ω RON matching between channels, and 0.1Ω RON flatness. These devices handle rail-to-rail analog signals while consuming less than 3µW of quiescent power. They are available in space-saving 16-pin thin QFN (3mm x 3mm) and TSSOP packages.
