One Channel Direct Drive Speech Controller
PWM: A PWM (pulse width modulation) circuit is built-in SNC11B. 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 SNC11B. With this advanced circuit, the chip is capable of driving
speaker directly without external transistors. The recommended application
circuit is illustrated as follows.
