MAX4782 Datasheet, PDF (1/16 Pages) Maxim Integrated Products – High-Speed, Low-Voltage, 0.7OHM CMOS Analog Switches/Multiplexers

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
(R_ON), with 0.3Ω R_ON matching between channels, and
0.1Ω R_ON 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.
