The ICL8038 is a precision oscillating integrated circuit with multiple waveform outputs. The frequency and duty cycle of the output waveform can also be controlled by current or resistance. Since the chip has an FM signal input, it can be used to frequency-modulate low-frequency signals. The kit is designed for the frequency range commonly used, divided into five stalls adjustable, can produce from 10Hz-450KHz low distortion sine wave, triangular wave, square wave pulse signal. Components parameters according to the original given values given in the selection, the circuit of integrated circuits, diodes, transistors, electrolytic capacitors are polar components, careful not to install the opposite direction. All components should be mounted on the circuit board surface. Each potentiometer has an influence on each other, please select the appropriate frequency band (J2 short-circuit cap) repeatedly carefully adjusted, the frequency is lower than 50Hz and higher than 200KHz is not recommended. Circuit power supply: 12-24V
