SGM3003
GENERAL DESCRIPTION
The SGM3003 is a single, low ON-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switches designed to operate from a single +1.8V to
+5.5V supply. Targeted applications include battery
powered equipment that benefit from low R
ON
(0.5Ω) and
fast switching speeds (t
ON
= 21 ns, t
OFF
= 9 ns).
The on resistance profile is very flat over the full analog
signal range. This ensures excellent linearity and low
distortion when switching audio signals.
SGM3003 has one normally open switch and one normally
closed switch，Each switch conducts equally well in both
directions when on.
SGM3003 is available in a MSOP-8 package.
Ultra Low ON-Resistance, Low

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.

Signals on NC, NO, or COM or IN exceeding V+ will be clamped by internal diodes. Limit forward diode current to maximum
current ratings.
