SGM4865
2.6W Stereo Audio Power Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM4865 is a stereo audio power amplifier that is
designed for demanding applications in mobile phones
and other portable communication device applications. It
is capable of delivering 2.6W of continuous average
power per channel into a 4Ω load with typically 10%
distortion (THD+N) from a 5V power supply.
The SGM4865 features an externally controlled, low
power consumption shutdown mode and thermal
shutdown protection. It also utilizes circuitry to reduce
“pop/click” during device turn-on.
The SGM4865 is unity-gain stable and can be configured
by external gain-setting resistors.
The SGM4865 is available in Green TQFN-4×4-16L
package. It operates over an ambient temperature range
of -40℃ to +85℃.
