CST8002D

The CST8002D is an audio power amplifier primarily designed for demanding applications in low-power portable systems.
       
CST8002D is capable of delivering 3 watts of continuous average power to an 3

    CST8002D General Description:

    The CST8002D is an audio power amplifier primarily designed for demanding applications in low-power portable systems. It is capable of delivering 3 watts of continuous average power to an 3Ω BTL load with less than 10%distortion (THD) from a 5VDC power supply. the CST8002D does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for audio systems and other low voltage applications where minimal power consumption is a primary requirement.
        The CST8002D features a low-power consumption shutdown mode. the CST8002D contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions.   
        The 
    CST8002D is unity-gain stable and can be configured by external gain-setting resistors.
        The CST8002D can provide your USB subwoofer, radio, MP3 player, and loudspeaker perfect solution.

       
    CST8002D Features:

    VDD=5VRL=3ΩPo=3WTHD+N10%

    Wide operating voltage range: 1.5V~5.5V

    Improved pop & click circuitry eliminates noise during turn-on and turn-off transitions

    Available in space-saving packages: SOP-8



    CST8002D Applications:
    Card inserting speaker, Bluetooth speaker
    Handheld game machine
    Low voltage audio systems
    IPC

    CST8002D Typical Application Circuit:
    注: 以上应用图中元件说明:
    Ci:隔直电容,采用 0.39µF或更小的,进一步消除咔嗒-噼 噗声和从输入端耦合进入的噪声。
    Cs:电源去耦电容,采用足够低ESR的电容(小于 1µF),当VDD=5V时,为更好的滤除低频噪声,建议另加一个低ESR电容(不小于 10µF)。去耦电容离VDD管脚越近越好,保持 1.5mm之内。
    CB : BYPASS端口输出VDD/2 电压,通过电容CB (1µF)接地以保证稳定性。
