Direct Drive Speech Controller
PWM: A PWM (pulse width modulation) circuit is built-in SNC20AS. PWM can
convert input digital data into pulse trains with suitable different pulse width. The
maximum resolution of PWM is 7 bits. Two huge output stage circuits are designed
in SNC20AS. With this advanced circuit, the chip is capable of driving speaker
directly without external transistors. The recommended application circuit is
illustrated as follows.
