Description

The BU8768FV is a tone generator IC for cellular phones that can produce triple chords simultaneously.

Tone and volume of BU8768FV in each sound source can be controlled separately by serial control. Master volume is integrated.

Output of BU8768FV can be selected from pseudo sine wave and special square wave. The special square wave is a waveform that can take sound pressure by even a small speaker.
