SGM44603
4.5Ω, High Speed, Low Voltage
Quad, SPDT Analog Switch
GENERAL DESCRIPTION
The SGM44603 is a high-speed, low-voltage, quad
single-pole/double-throw (SPDT) CMOS analog switch
multiplexer that is designed to operate from a single
+1.8V to +5.5V power supply.
SGM44603 features guaranteed on-resistance (4.5Ω
TYP), on-resistance matching (3.6Ω MAX) between
switches and guaranteed on-resistance flatness over the
signal range (3Ω TYP). This ensures excellent linearity
and low distortion when switching audio signals. Fast
switching speed, coupled with high signal bandwidth
(300MHz), also makes the parts suitable for video signal
switching. CMOS construction ensures ultra low power
dissipation, making the parts ideally suited for portable
and battery powered instruments.
SGM44603 is available in Green TQFN-2.6×1.8-16L
package.

NOTES:
1. Signals on NC, NO, or COM or IN
X
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 last datasheet.
