    SGM4810

    Dual 158mW Headphone Amplifier with Active High Shutdown Mode
     
    Dual 158mW Headphone Amplifier with Active High Shutdown Mode
    GENERAL DESCRIPTION

    The SGM4810 is a dual audio power amplifier capable of delivering 158mW per channel of continuous average power with typically 0.1% distortion (THD+N) when it drives a 16Ω speaker from a 5.0V power supply. It is designed to maximize audio performance in portable applications such as mobile phone. The portable application requires audio power amplifier has minimum of external components and can operate from a single 2.5V to 5.5V power supply.

    SGM4810 features an externally controlled, active-high, micro-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

    The SGM4810 does not require bootstrap capacitors or snubber networks. It is optimally suited for low power portable systems.

    For maximum flexibility, the SGM4810 provides an externally controlled gain (with resistors), as well as an externally controlled turn-on time (with the bypass capacitor).

    The SGM4810 is available in a Green MSOP-8 package. It operates over an ambient temperature range of -40 to +85.
