SGM4808
Wide Power Supply Range
Audio Click-Pop Noise Eliminator
GENERAL DESCRIPTION
FEATURES
The SGM4808 is an audio click-pop eliminator which
can operate from a 2.7V to 12V single power supply. It
is designed for HiFi audio system or portable devices.
● Supply Voltage Range: 2.7V to 12V
● Low On-Resistance: 1.1Ω (TYP)
● -VCC to +VCC Rail-to-Rail Low Distortion Audio
Signals Passing
The SGM4806 allows -VCC to +VCC wide range audio
signals passing with low distortion. An external
processor can eliminate the click-pop noise.
● Fast Switching Times
● High Off-Isolation
● Low Crosstalk
The SGM4808 is available in Green TQFN-2.6×1.8-16L
and SOIC-16 packages. It operates over an ambient
temperature range of -40℃ to +85℃.
● 1.8V Logic Control
● -40℃ to +85℃ Operating Temperature Range
● Available in Green TQFN-2.6×1.8-16L and
SOIC-16 Packages

OVERSTRESS CAUTION
Stresses beyond those listed in Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods
may affect reliability. Functional operation of the device at any
conditions beyond those indicated in the Recommended
Operating Conditions section is not implied.

ESD Susceptibility
ESD SENSITIVITY CAUTION
This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failureto observe proper handlingand installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

NOTE:
1. Signals on RIN, LIN, ROUT, LOUT, exceeding VCC will be
clamped by internal diodes. Limit forward diode current to
maximum current ratings.
