High-Speed, Low-Voltage, 0.7Ω CMOS Analog
Switches/Multiplexers
Features
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 16pin thin QFN (3mm x 3mm) and TSSOP packages.
