Simple but powerful Function generator

Posted on January 12, 2007 | 2 Comments

The generator was build and tested by nuxie1 using XR-2206 function generator IC, which is capable to generate sine, square, ramp and pulse waveforms in frequency range of 0.01Hz to 1MHz. The amplitude and frequency is modulated by voltage (potentiometers). The example circuit from datasheet worked well:

Second step – project creation. Project Eagle files can be found here.

Finished board:

Final phase – testing. The signal generator produced clean and nice signal in frequency range between 1Hz and 1Mhz.
