ICL8038 Function Signal Generator Kit Multi-channel

Note: This is a DIY kit, you need to assemble it.ature: 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. Circuit principle: ICL8038 pin function:1 pin, 12 pin: sine wave adjustment side2 pin: sine wave output3 pin: triangular wave output4 pin, 5 pin: frequency and duty cycle (or waveform asymmetry) adjustment6 pin: V , positive power supply7 pin: frequency offset8 pin: frequency adjustment input9 pin: square wave output. This is an open collector output. When working, connect a load resistor from the pin to the corresponding positive supply, to obtain a TTL-compatible square wave output, the load resistor must be connected to the 5V supply.10 pin: timing capacitor side11 pin: V-, negative power supply terminal connect ground. When using positive and negative power supply, 11 pin connected to the negative power supply, the output waveform is relative to 0V symmetry. When using a single positive power supply, pin 11 is grounded and the output waveform is unipolar and the

With excellent performance ASIC chip function generator ICL8038, add a small amount of resistive and capacitive components, can produce sine, triangle and square wave, and the frequency of the signal, duty cycle, adjustable distortion sine wave.
