    STPA001
    Description
    The STPA001 is a breakthrough MOSFET technology class AB audio power amplifier designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.
    网上最靠谱的赚钱方法 The STPA001 can operate down to 6V and this make the IC compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' battery profile during engine stop), helping car manufacturers to reduce the overall emissions and thus contributing to environment protection.

    TDA2004R
    Description
    The TDA2004R is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications.
    Power booster amplifiers can be easily designed using this device that provides a high current capability (up to 3.5 A) and can drive very low impedance loads (down to 1.6 Ω).
    The TDA2004R allows very compact applications because few external components are required and it doesn't need electrical insulation between the package and the heatsink.
    Key Features
    Low distortion
    Low noise
    Protection against:
    Output AC short circuit to ground
    Overrating chip temperature
    Load dump voltage surge
    Fortuitous open ground
    Very inductive loads

    TDA2005
    Description
    The TDA2005 is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications.
    Power booster amplifiers can be easily designed using this device that provides a high current capability (up to 3.5 A) and can drive very low impedance loads (down to 1.6 Ω in stereo applications) obtaining an output power of more than 20 W (bridge configuration).
    Key Features
    High output power:
    Po = 10 + 10 W @ RL = 2 Ω, THD = 10 %
    Po = 20 W @ RL = 4 Ω , THD = 10 %.
    Protection against:
    Output DC and AC short circuit to ground
    Overrating chip temperature
    Load dump voltage surge
    Fortuitous open ground
    Very inductive loads
    Loudspeaker protection during short circuit for one wire to ground

    TDA7350A
    Description
    The TDA7350A is a new technology class AB Audio Power Amplifier in the Multiwatt? package designed for car radio applications.
    Thanks to the fully complementary PNP/NPN output configuration the high power performance of the TDA7350A is obtained without bootstrap capacitors.
    A delayed turn-on mute circuit eliminates audible on/off noise, and a novel short circuit protection system prevents spurious intervention with highly inductive loads.
    Key Features
    VERY FEW EXTERNAL COMPONENTS
    NO BOUCHEROT CELLS
    NO BOOSTRAP CAPACITORS
    HIGH OUTPUT POWER
    NO SWITCH ON/OFF NOISE
    VERY LOW STAND-BY CURRENT
