MAX4781

High-Speed, Low-Voltage, 0.7Ω CMOS Analog Switches/Multiplexers

Maxim Integrated 

19-2522; Rev 3; 2/05

High-Speed, Low-Voltage, 0.7Ω CMOS Analog

Switches/Multiplexers

General Description

The MAX4781/MAX4782/MAX4783 are high-speed,

low-voltage, low on-resistance, 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

(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 qui-

escent power. They are available in space-saving 16-

pin thin QFN (3mm x 3mm) and TSSOP packages.
