产品参数

描述

The SGM4866 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 1.28W ofcontinuous average power per channel into an 8Ω Bridge Tied Load (BTL) with less than 1% distortion (THD+N) from a 5V power supply.
The SGM4866 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 SGM4866 is unity-gain stable and can be configured by external gain-setting resistors.
 The SGM4866 is available in Green TQFN-3×3-16L package. It operates over an ambient temperature range of -40°C to +85°C.
