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

), 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.

50Ω, Low-Voltage, Quad SPST/Dual SPDT Analog Switches in WLP Test Circuits/Timing Diagrams Operating Considerations for High-Voltage Supply The MAX4747–MAX4750 operate to +11V with some precautions. The absolute maximum rating for V+ is +12V (referenced to GND). When operating near this region, bypass V+ with a minimum 0.1µF capacitor to ground as close to the IC as possible.
