SGM4996
1.3W Fully Differential Audio Power
Amplifier with Selectable Shutdown
MARCH 2017 – REV. A. 3

GENERAL DESCRIPTION
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 in
to an 8Ω load with typically
1% distortion (THD+N) from a 5V battery voltage. It
operates from 2.5V to 5.5V power supply.
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.
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.
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℃.
