1. The HY-100 series music integrated circuit. The HY-100 series music IC is a large-scale CMOS IC. This circuit integrates the total circuit, which includes the preamplifier and power amplifier circuit, to a 25mmx15mm PCB by using the CMOS technology. This chip has been soldered a 68kΩ resistance which is shown in the picture. The picture shows the HY-100 series music IC. The HY-100 series IC has the features of big driving capacity and flexible output port operation. Its pin 5 is power output port which can drive the loudspeaker directly. Its pin 3, pin 4 are preamplifier's output ports which can drive the piezoelectric buzzer working and driving the semiconductor diode. The HY-100 series music IC is a circuit can be used as doorbell. When the positive pulse triggers the pin 2 trigger port, it would play the music sound automatically about 20s.
