    TS4909IQT

    Ultra low power stereo headphone amplifier with capacitor-less output

    Parameters
    Supply Voltage Min Volt2.2
    Supply Voltage Max Volt5.5
    Operating Temp Min Celsius-40.0
    Operating Temp Max Celsius85.0
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack1
    GradeIndustrial
    Package NameVDFPN 10 3x3x1.0
    Description

    The TS4909 is a stereo audio amplifier designed to drive headphones in portable applications. The integrated phantom ground is a circuit topology that eliminates the heavy output coupling capacitors. This is of primary importance in portable applications where space constraints are very high.
