XR Datasheet – Monolithic Function Generator – Exar

With the component values shown above, the overlapping frequency ranges are shown in the following table: The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. The actual sample structure differs in some details from the data sheet. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency.

Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same.

It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.


The output waveforms xf be both amplitude and frequency modulated.

Function Generator with XR2206

A common function generator provides sine, for example, triangular and square waves. It also analyzes transistor’s characteristics such as voltage and gain.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

With the frequency-determining capacitor of 0. The frequency is changed by using a variable resistor.

Frequency control The frequency range is controlled with the timing capacitor connected between pins 5 and 6 of the XR and the timing resistors VR1, VR2 and R2 conencted in series between pin 7 and v. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.

But there are some points that could improve it take to build an almost professional function generator. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Many attempts have come out with this simple circuit.

The sample design renounces everything that is not absolutely necessary. The frequency must be adjustable and at least cover the low frequency range. Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses an ATmega as a frequency counter and to drive an 8-digit 0. Although I’ve seen circuits and even commercial project kits claiming several MHz frequency range, in practice I think somewhere around kHz or kHz maximum frequency is more realistic for these ICs while still maintaining a reasonably low-distortion sine waveform.


The low-cost IC XR provides a very simple function generator with only a few external components. XR data sheet provides complete basic circuit for a simple function generator. It requires an operating voltage of 12 V and delivers sine and square wave signals. On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with alligator clips.

Function Generator with XR Instead of the sine wave output is obtained after opening of S1 a triangular output wave. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. The additional output at pin 11 also delivers datsaheet square wave with the same frequency.

Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption may be supplied from a single 9V battery.
