icl 8038 โมดูลเครื่องกําเนิดสัญญาณ diy kit

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：
It is an welded product if you need the DIY kit pls contact us : ）

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.
