MAX4748EBE+T

P1-P3P4-P6P7-P9P10-P12P13-P14
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 50Ω (max) on-resistance (R
ON
), with 3.5Ω (max)
matching between channels and 9Ω (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 TQFN (4mm x 4mm),
and 16-bump WLP packages. This tiny chip-scale pack-
age occupies a 2mm 2mm area and significantly
reduces the required PC board area.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
