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 weld the kit yourself. Description: 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. Model: ICL8038 Input 12V DC Frequency range: 50-5KHz Size: 6cm*4.5cm*0.2cm Weight:26g Package Included: 1 set function signal generator module DIY Kits
