50鈩?Low-Voltage, Quad SPST/Dual SPDT Analog
Switches in UCSP
General Description
The MAX4747鈥揗AX4750 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
庐
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鈩?(max) on-resistance (R
ON
), with 3.5鈩?(max)
matching between channels and 9鈩?(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 and 16-bump chip-scale
packages (UCSP鈩?. This tiny chip-scale package occu-
pies a 2mm
