High-Speed, Low-Voltage, 0.7Ω CMOS Analog
Switches/Multiplexers
General Description
Features
♦ On-Resistance
0.7Ω (+3V Supply)
1.6Ω (+1.8V Supply)
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).
♦ On-Resistance Match Between Channels
0.3Ω (+3V Supply)
♦ On-Resistance Flatness
0.1Ω (+3V Supply)
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
♦ Single-Supply Operation Down to 1.6V
♦ High-Current Handling Capacity (150mA
(R ), with 0.3Ω R
matching between channels, and
ON
flatness. These devices handle rail-to-rail
ON
0.1Ω R
Continuous)

♦ +1.8V CMOS-Logic Compatible
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.
♦ Fast Switching Times: t
= 11ns, t
= 4ns
