SGM3799
0.5Ω, Low Voltage
Dual, DPDT Analog Switch
GENERAL DESCRIPTION
The SGM3799 is a dual, ultra low on-resistance, low
voltage, double-pole/double-throw (DPDT) CMOS analog
switch. This device is designed for low operating voltage,
high current switching of speaker output and earpiece for
cellphone applications. It can switch a balanced stereo
output.
The SGM3799 can handle a balanced microphone/
speaker/ring-tone generator in a monophone mode. It
contains a break-before-make (BBM) feature.
The SGM3799 is configured as a dual double-pole/
double-throw (DPDT) analog switch with two logic control
inputs that control two SPDT switches each. The
configuration can be used as a dual differential 2-to-1
multiplexer/demultiplexer.
The SGM3799 is available in Green TQFN-2.6×1.8-16L
package.

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.
