    Docket ↓
    LM4952 SNAS230A – AUGUST 2004 – REVISED MAY 2013 LM4952 Boomer™ Audio Power Amplifier Series 3.1W Stereo-SE Audio Power Amplifier
    with DC Volume Control
    Check for Samples: LM4952 FEATURES DESCRIPTION The LM4952 is a dual audio power amplifier primarily
    designed for demanding applications in flat panel
    monitors and TV's. It is capable of delivering 3.1
    watts per channel to a 4Ω single-ended load with less
    than 1% THD+N when powered by a 12VDC power
    supply. 1 23 Pop & Click Circuitry Eliminates Noise During
    Turn-on and Turn-off Transitions
    Low Current, Active-low Shutdown Mode
    Low Quiescent Current
    Stereo 3.8W Output, RL = 4Ω
    DC-controlled Volume Control
    Short Circuit Protection APPLICATIONS Flat Panel Monitors
    Flat Panel TV's
    Computer Sound Cards KEY SPECIFICATIONS Quiscent Power Supply Current 18mA (typ)
    POUT @
    VDD = 12V, RL = 4Ω, 10% THD+N 3.8W (typ)
    Shutdown current 55μA (typ) Eliminating external feedback resistors, an internal,
    DC-controlled, volume control allows easy and
    variable gain adjustment.
