Function Generator DIY Kit 20Hz - 100KHz
Review of XR2206 Function Generator DIY Kit
Function generator is an integral part of any electronic lab. This test equipment used to generate different types of electrical waveforms: usually sine, triangle, sawtooth and square waves. More information about function generators can be found on Wikipedia.
Some Integrated Circuits was designed to generate waveforms and it possible to build your own diy function generator project based on this type of IC. One of this chips is XR2206 by EXAR.
XR2206 is monolithic function generator IC with excellent temperature stability 20ppm/C, wide sweep range, low sine wave distortion and other features.
Our diy function generator kit has all components to build a simple diy project:
All components is carefully packed with different suitable bags:
The PCB board is double side with green soldermask and white silkscreen for easy parts installation. The board is high quality manufactured with through pads and HASL.
The diy function generator kit can produce sine, triangle and square waves from 20Hz to 100KHz in 4 ranges with fine adjust. It can be powered from 12V DC power supply and consume 20mA current.

The kit is can be used without calibration that may be relevant if you can't reach a oscilloscope. Without sine wave calibration it has 2.5% total harmonic distortion (THD). If you'll perform calibration process it will reach 0.5% THD.
The circuit and full PDF manual is included in the purchase. The manual has pictures of the assembling process and calibration instruction. The kit is require solder skills and basic electronics knowledge. However we can offer a technical support.
The board has jumper control for frequency range selection. 4 high quality polyester timing capacitors is provide each range:
- 20Hz- 100Hz
- 100Hz - 1KHz
- 1KHz - 10KHz
- 10KHz - 100KHz
