SGM3005
Ultra Low ON-Resistance,
Low Voltage, Dual, SPDT Analog Switch
GENERAL DESCRIPTION
The SGM3005 is a dual, low on-resistance, low voltage,
bidirectional, single-pole/double-throw (SPDT) CMOS
analog switch designed to operate from a single 1.8V to
5.5V power supply. Targeted applications include battery
powered equipment that benefit from low R
ON
(0.5Ω) and
fast switching speeds (t
ON
= 50ns, t
OFF
= 15ns).
The on resistance profile is very flat over the full analog
signal range. This ensures excellent linearity and low
distortion when switching audio signals.
The SGM3005 is a committed dual single-pole/double-
throw (SPDT) that consist of two normally open (NO) and
two normally close (NC) switches. This configuration can
be used as a dual 2-to-1 multiplexer.
SGM3005 is available in Green TDFN-3×3-10L and
MSOP-10 packages.

NOTES:
1. Signals on NC, NO, or COM or IN exceeding V
+
will be clamped by internal diodes. Limit forward diode current to maximum current
ratings.
2. 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.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause
damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.
SGMICRO reserves the right to make any change in circuit design, specification or other related things if necessary without notice at
any time. Please contact SGMICRO sales office to get the latest datasheet.
