SGM4865 2.6W Stereo Audio Power Amplifier

GENERAL DESCRIPTION

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.
