    Dual 2.1W Audio Power Amplifier Plus Stereo Headphone Function
     
    Dual 2.1W Audio Power Amplifier Plus Stereo Headphone Function
    GENERAL DESCRIPTION

    The SGM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W into a 4Ω load or 2.5W into a 3Ω load with typically 1% THD+N. In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.

    To simplify audio system design, the SGM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.

    The SGM4863 features a low power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop/click” during device turn-on.

    The SGM4863 is available in Green TSSOP-20 (Exposed Pad), TQFN-3×3-20L, TSSOP-16 (Exposed Pad), SOIC-16 and DIP-16 packages. It operates over an ambient temperature range of -40 to +85.
