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

) and 0.6Ω

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.
