DIY ICL8038 Function Signal Generator Module Sine Square Triangle Wave Output KIT 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. Model: ICL8038 Input: 12V DC Frequency range: 50-5KHz, Size: 6cm*4.5cm*0.2cm Package Included: 1 x DIY ICL8038 Function Signal Generator Module Sine Square Triangle Wave Output KIT
