CLASS-D Power Amplifier

XS8302,XS8302M

   The XS8302,XM8302M is an audio power amplifier primarily designed for demanding applications in low-power portable systems.
    It is capable of delivering 5 watts of continuous average power to a 2Ω BTL load with less than 10% distortion (THD) from a 5.5V DC power supply. 

    XS8302,XM8302M General Description:
        The 
    XS8302,XM8302M is an audio power amplifier primarily designed for demanding applications in low-power portable systems. It is capable of delivering 5 watts of continuous average power to a 2Ω BTL load with less than 10% distortion (THD) from a 5.5V DC power supply. 
        The 
    XS8302,XM8302M does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
        The 
    XS8302,XM8302M features a low-power consumption shutdown mode.
        The 
    XS8302,XM8302M contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions.
        The 
    XS8302,XM8302M can be configured by external gain-setting resistors.
        The 
    XS8302,XM8302M integrates overheating protection mechanism, The XS8302,XM8302M is unity-gain stable and can be configured by external gain-setting resistors.
        The 
    XS8302,XM8302M can provide your USB subwoofer, radio, MP3 player, and loudspeaker perfect solution.

    XS8302,XM8302M Typical Application Circuit:

    注: 以上应用图中元件说明:
        Ci:隔直电容,采用 0.1µF 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。
    INBYP: INBYP 端口输出 VDD/2 电压,通过电容 C B (1µF)接地以保证稳定性。如 PCB 方案设计时需考虑与其它同类型产品的兼容性,可预留电阻R0 位置,生产贴片时采用 0 欧姆电阻即可;如不需要考虑与其它同类型产品的兼容性,可去掉电阻 R0,直接短接即可。
