Feature:
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.
Notice:
Requires a certain DIY ability, you need to soldering the kit yourself : )
Description:
ICL8038 pin functions:
Pin 1, Pin 12: sine waveform adjusting terminal;
Pin 2: sine wave output;
Pin 3 : triangle wave output;
Pin 4 , Pin 5 : the frequency and duty cycle (or waveform asymmetry) adjustment;
Pin 6 : V +, the positive power supply;
Pin 7 : Frequency Offset;
Pin 8 : Frequency adjustment input terminal;
Pin 9 : square wave output. This is an open collector output terminal, work should take a load resistor to the corresponding positive power supply terminal from the pin, to get a TTL-compatible square-wave output, the load resistance must be connected to + 5V power supply;
Pin 10 : timing capacitor terminal;
Pin 11 : V-, negative power supply terminal or the ground. When Use positive and negative power supply, Pin 11 to the negative supply, the output waveform are symmetrical with respect to 0 V; When use a single positive power supply, Pin 11 grounded, the output waveform is unipolar, uniform voltage is + VCC / 2;
Pin 13 and Pin 14 : Empty Pin.
The kit is designed for a frequency range is 50-5KHz, two bands with using a switch S to switch, RP1 is the frequency adjustment, RP2 is the duty cycle adjustment, RP3 is a sine wave distortion adjustment. Circuit uses 12V single power supply, input from the X1; X2, X3 is a waveform output side, you can use oscilloscope to observe three output waveforms.
