General Description
The MAX4731/MAX4732/MAX4733 low-voltage, dual,
single-pole/single-throw (SPST) analog switches oper-
ate from a single +2V to +11V supply and handle rail-
to-rail analog signals. These switches exhibit low
leakage current (0.1nA) and consume less than 0.5nW
(typ) of quiescent power, making them ideal for battery-
powered applications.
When powered from a +3V supply, these switches fea-
ture 50
(max) on-resistance (R
ON
) with 3.5
(max)
matching between channels, and 9
(max) flatness
over the specified signal range.
The MAX4731 has two normally open (NO) switches,
the MAX4732 has two normally closed (NC) switches,
and the MAX4733 has one NO and one NC switch. The
MAX4731/MAX4732/MAX4733 are available in 9-bump
chip-scale packages (UCSP), along with 8-pin TDFN
and 8-pin μMAX
packages. The tiny UCSP occupies a
1.52mm
1.52mm area and significantly reduces the
required PC board area.
