Note:THis product is DIY kit,need to conduct their own welding assembly,shipping package with instructions,schematics,bill of when to get kits,please inventory components prior to welding,component devices are small objects,easy to fall.according to lists and board ,patient carefully,can be weld successfully!

ICL8038 is an Excellent performance monolithic function signal generator ASIC, It only need connect external small amounts of RC components can Product sine wave, triangular wave and square wave.

Circuit use the 12 v single power supply
ICL8038 pin function:
1.foot,12 foot:Sine waveform adjustment terminal
2.foot:sine wave output.
3.foot:Triangle wave output.
4 foot 5 foot:Frequency and duty ratio (or waveform asymmetric ) adjustment;
6 foot: V +, the positive power supply
7 foot: frequency offset
8 foot: frequency adjust the input side
9 foot: square wave output.This is an open collector output terminal,should Work from the pin is connected to a load resistor to the the corresponding positive power supply terminal,to get a TTL-compatible square-ware output the load resistance Must be connect to + 5 v power supply

10 foot: the timing capacitor terminal
11 foot: V -, negative power supply side or grounded.When using the positive and negative power supply,11 feet connect negative power supply.the output waveform are symmetry with respect to 0 v,Using a single positive power supply,11 feet grounded,The output waveform is Unipolar,And uniform voltage is + VCC / 2;
13 foot, 14 foot: empty foot

The kit are Design for a Frequency range is 50-5 KHZ,with Two frequencies,With the switch S to Handover,RP1 is frequency adjustment,RP2 is duty ratio adjustment,RP3 is sine wave distortion adjustment,Circuit use the 12 v single power supply,input from X1 ,X2, X3 is waveform output,Can use the oscilloscope observation three output waveform.
