MAX4706EXK+T

P1-P3P4-P6P7-P9P10-P11
General Description
The MAX4706/MAX4707 single-pole/single-throw
(SPST) switches operate from a single 1.8V to 5.5V sup-
ply. The MAX4706 is a normally closed (NC) switch and
the MAX4707 is the normally open (NO) version. These
switches provide 2Ω on-resistance (R
ON
) and 0.6Ω
R
ON
flatness with a +2.7V supply. These devices typi-
cally consume only 0.02µA of quiescent current, mak-
ing them suitable for use in low-power, portable
applications. The MAX4706/MAX4707 feature low-leak-
age currents over the entire temperature range,
TTL/CMOS-compatible digital logic, and excellent AC
characteristics.
The MAX4706/MAX4707 are offered in small 5-pin and
6-pin SC70 and 6-pin µDFN packages.
