SGM4996
1.3W Fully Differential Audio Power
Amplifier with Selectable Shutdown
GENERAL DESCRIPTION
FEATURES
The SGM4996 is a fully differential audio power
amplifier that is designed for portable communication
device applications and demanding applications in
mobile phones. It is capable of delivering 1.3W of
continuous average power into an 8Ω load with typically
1% distortion (THD+N) from a 5V battery voltage. It
operates from 2.5V to 5.5V power supply.
• Fully Differential Amplifier
• Excellent PSRR: Direct Connection to Battery
• 1.3W into 8Ω Load from 5V Supply at
THD+N = 1% (TYP)
• 2.5V to 5.5V Operation
• Low Shutdown Current
• Improved Pop/Click Circuitry
• Support Single-Ended or Differential Input
• Thermal Overload Protection Circuitry
• No Output Coupling Capacitors, Bootstrap
Capacitors Required
The SGM4996 features a low power consumption
shutdown mode. To be flexible, shutdown may be
enabled by either a logic high or low depending on the
voltage applied on the SD MODE pin. Additionally, the
SGM4996 features an internal thermal shutdown
protection mechanism.
• External Gain Configuration Capability
• -40℃ to +85℃ Operating Temperature Range
• Available in Green MSOP-10, TDFN-3×3-10L and
MSOP-8 Packages
The SGM4996 contains advanced pop/click circuitry,
with a minimal amount of external components. All
these features make SGM4996 ideal for wireless
handsets and other low voltage applications where
minimal power consumption is a primary requirement.
APPLICATIONS
Portable Systems
Wireless Handsets
Mobile Phone
Handheld Computers
PDAs
The SGM4996 is available in Green MSOP-10,
TDFN-3×3-10L and MSOP-8 packages. It operates
over an ambient temperature range of -40℃ to +85℃.

ESD SENSITIVITY CAUTION
ABSOLUTE MAXIMUM RATINGS
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.
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 very small parametric changes could cause the
device not to meet its published specifications.

DISCLAIMER
SG Micro Corp reserves the right to make any change in
circuitdesign, specificationor other related things if necessary
without notice at any time.
OVERSTRESS CAUTION
Stresses beyond those listed may cause permanent damage
to the device. Functional operation of the device at these or
any otherconditions beyond those indicated in the operational
sectionof thespecificationis not implied. Exposureto absolute
maximum rating conditions for extended periods may affect
reliability.
