Generador De Funciones Icl8038 Cuadrada Triangular Senoidal Itytarg

ICL8038 pin functions: 
1 foot, 12 foot: sine waveform adjusting terminal; 
2 foot: sine wave output; 
3 foot: triangle wave output; 
4 foot, 5 foot: the frequency and duty cycle (or waveform asymmetry) adjustment; 
6 foot: V +, the positive power supply; 
7 foot: offset; 8 foot: frequency adjustment input terminal; 
9 foot: 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; 
10 foot: timing capacitor terminal; 
11 foot: V-, negative power supply terminal or the ground. Use positive and negative power supply, 11 feet to the negative supply, the output waveform are symmetrical with respect to 0V; use a single positive power supply, 11 feet grounded, the output waveform is unipolar, uniform voltage is + VCC / 2; 
13 feet, 14 Feet: Empty foot. 
The kits are designed for a frequency range is 50-5KHz, two bands with 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.
