1Hz to 1MHz Function Generator with XR-2206 IC

Frequency Generator is an essential laboratory equipment for every electronic. It allows a variety of measurements and experiments. The module described here is based on high quality XR2206 IC and is extremely compact and inexpensive. Output frequency is from 1Hz to 1MHz. It provides sine, square and triangle waves around 1Hz to 1MHz, depending on the timing capacitors used. Over two Potentiometers the amplitude and frequency can be set. About trimmers can also have the purity of the sine signal and the offset of the output voltage can be changed.
