General Description

The MAX4747–MAX4750 low-voltage, quad single-pole

single-throw (SPST)/dual single-pole/double-throw

(SPDT) analog switches operate 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

matching between channels and 9

Ω (max) flatness

over the specified signal range.

The MAX4747 has four normally open (NO) switches, the

MAX4748 has four normally closed (NC) switches, and

the MAX4749 has two NO and two NC switches. The

MAX4750 has two SPDT switches. These switches are

available in 14-pin TSSOP, 16-pin thin QFN (4mm x

4mm), and 16-bump chip-scale packages (UCSP™). This

and significantly reduces the required PC board area.
