SGM4866

  GENERAL DESCRIPTION SGM4866 1.28W Stereo Audio Power Amplifier FEATURES 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 of continuous average power per channel into an 8Ω bridge tied load (BTL) with typically 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 “pop/click” 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℃ to +85℃.  1.28W into 8Ω BTL Load from 5V Supply at THD+N = 1% (Typical, per Channel)  Excellent PSRR: Direct Connection to Battery  Unity Gain Stable  2.6V to 5.5V Operation  ...
