KD0071 IC Typical Application Circuit

Published:2011/7/4 7:46:00 Author:Robert | Keyword: IC, Typical, Application | From:SeekIC

The KD0071 is a single-chip sound-conversion IC which is adequate for the sound generating circuits in many kinds of toys and Kara OK'a tonal modification. The KD0071 IC has internal oscillation circuit, trigger circuit, A/D (analog/digital) conversion circuit, and other some auxiliary circuits. The sound-conversion circuit typical application circuit composed of KD0071 IC is shown in the picture. It should be noted that SA3 is the control switch of the robot's sound effect. When it is closed the speaker would play the sound of the robot sound effect. The SB is sound effect conversion switch. Each time it is pressed the sound effect would has a conversion. The R4, C8 is frequency-selecting elements of the oscillation clock. The picture shows the KD0071 IC's typical application circuit.
