SGM44602
4Ω, High Speed, Low Voltage
Dual, DPDT Analog Switch
GENERAL DESCRIPTION
The SGM44602 is a dual, high-speed, low-voltage,
double-pole/double-throw (DPDT) CMOS analog switch
that is designed to operate from a single 1.8V to 5.5V
power supply. It features high-bandwidth (300MHz) and
low on-resistance (4Ω TYP), targeted applications for
audio switching.
The SGM44602 consists of four SPDT switches. The
configuration can be used as a bidirectional quad
2-channel multiplexer/demultiplexer with a single switch-
enable (IN
1-4
) input.
SGM44602 can handle rail-to-rail analog signals and is
available in Green TQFN-2.6×1.8-16L package.
FEATURES
Low Voltage Operation: 1.8V to 5.5V
Low On-Resistance: 4Ω (TYP)
Low On-Resistance Flatness
-3dB Bandwidth: 300MHz
High Off-Isolation: -75dB at 1MHz
Low Crosstalk: -100dB at 1MHz
Rail-to-Rail Input and Output Operation
Typical Power Consumption (<0.01µW)
TTL/CMOS Compatible
Available in Green TQFN-2.6×1.8-16L Package
Extended Industrial Temperature Range:
-40℃ to +85℃

NOTE:
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 last datasheet.
