摘要

在消费类电子产品中，相对于“旧的”模拟处理，音频信号的数字处理正变得优选。最后一个仍然具有模拟输入和全模拟处理的模块是音频功率放大器。由于高密度BCD技术，现在可以实现具有数字输入的低成本单芯片音频功率放大器。本文给出了两个例子，分别探讨了开关技术(PWM)和线性ab类输出级。

Digital input audio power amplifiers in 0.6-/spl mu/m BCD technology: two examples

In consumer electronics, the digital processing of the audio signal is becoming preferred with respect to the "old" analog processing. The last block still with analog input and full analog processing is the audio power amplifier. Thanks to the high-density BCD technology it is now possible to implement a low-cost single-chip audio power amplifier with digital input. In this paper two examples are presented, exploring respectively the switching technique (PWM) and the linear class-AB output stage.
