Signals
Pad No. Signal Name
Cout
Cout is tristate during standby.
Cout has zero current output when sound data is zero. Cout has full current output when sound data is the
highest. Cout has half of full current output when sound is silence at middle data value. Cout has half of full
current output when playing sound at appended memory-less mute.
The bypass Cout Resistor is used to bypass the audio output current from Cout. This bypassing extra current to
ground gives a way to prevent the saturation of audio waveform amplified by transistor. This Resistance is 470
ohm typically. It always is not very small. Or user can let it open if the transistor has a fair beta value.
A transistor with beta value 150 is sufficient for typical applications. Larger beta value get larger sound but may
have the amplified waveform saturated.
