CIC38 Series Music Integrated Circuit
CIC38 Series Music Integrated Circuit
CIC38 series music integrated circuit can directly drive the piezoelectric ceramics buzzer, as shown in figure (a). When the power supply voltage VDD is 3V, it can promote the piezoelectric ceramic buzzer and the light-emitting diodes at the same time, the application circuit is as shown in figure (b). If you want to get a larger volume, you can connect an amplifier transistor V T1 (9013 or 8050) externally to drive the horn, the specific circuit is as shown in figure(c).
