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 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 "clicks and pops" 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°C?to +85°C.
