  3. Function Generator DIY XR2206 Kit

    Function Generator XR2206 DIY Kit 20Hz - 100KHz

    $29.95

    Out of stock

    XR2206 Function Generator DIY Kit 20Hz - 100KHz

    Very simple DIY Kit of Function Generator based on XR2206 IC. The circuit was taken from the datasheet and adapted to our project condition.

    The kit is not require calibration! But also has components included in case you want to have full control on it with a oscilloscope for calibration to 0.5% THD.

    XR2206 Function Generator Kit is produce high quality Sine and Triangle wave outputs with high stability and accuracy. Square wave output is open collector type and can't be calibrated because of peculiar properties of the IC.

    Technical Specification:

    • Frequency's: 20Hz to 100KHz in 4 ranges with fine adjust Waveforms: Sine, Triangle, Square
    • Supply Voltage: 12V
    • Supply Current: 12-20mA
    • PCB Dimensions: 73 x 38 mm
    • Shipping Weight: 250 gr
    • UPC Number: 635346988677
    • SKU: RH-K-FG-XR2206

  4. XR2206-DIY-Function-Generator-www.radiohobbystore.com

    PCB for Function Generator XR2206 DIY Kit 20Hz - 100KHz

    $4.95

    PCB for DIY Function Generator XR2206 Kit 20Hz - 100KHz

    High Quality Printed Circuit Board with green solder mask. The PCB is for DIY XR2206 Function Generator. The Circuit is in description. Please refer XR2206 datasheet documentation for the information about components explanation.

    The frequency range capacitor C4 - C7 on the PCB is selected by jumper, or you can connect 1 Pole 4 Position Rotary Switch. Sine or Triangle Wave output can also be toggled with jumper or with external button.

    The PCB has separate outputs for Square Wave and Sine/Triangle Wave forms. Outputs are duplicated so that you can connect a frequency counter.

    If you can't reach a oscilloscope to calibrate the XR2206 Function Generator, then do not install R7 trimmer and adjust R8 to 200 ohm before power up the device!
