SGM3157
4.5Ω Low Voltage SPDT
Analog Switch in 6-Pin SC70
GENERAL DESCRIPTION
The SGM3157 is a single, bidirectional, single-pole/
double-throw (SPDT) CMOS analog switch that is
designed to operate from a single +1.8V to +5.5V
supply. It features high-bandwidth (300MHz) and low
on- resistance (4.5Ω TYP), Targeted applications for
audio switching.
SGM3157 features guaranteed on-resistance matching
(0.3Ω
MAX)
between
switches
and
guaranteed
on-resistance flatness over the signal range (2.3Ω TYP).
This ensures excellent linearity and low distortion when
switching audio signals.
SGM3157 is available in Green SC70-6 package.

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.
