<DIV>I am using ST micro's STM32F103 chip with their AN2812 development
code. It uses a PWM output, resulting in low-quality sound. Can I
just use a scaled version of the PWM to drive a DAC? (i.e. is the output linear,
or is there shaping to make the PWM output work?)</DIV>

<DIV>Any feedback, links or pointers would be greatly appreciated.</DIV>
