摘　　要：通过优化工艺条件降低Vpnp的饱和压降,提高音频功放的输出功率,同时调整BNH包DBP的尺寸,消除了漏电,使音频功放IC实现量产。By optimizing the process conditions to reduce the saturation voltage drop of Vpnp, we improved the output power of audio power amplifier, and adjusted the size of BNH in package DBP so that the leakage was eliminated. The audio power amplifier IC was achieved in mass production.
