The XR is a monolithic function generator integrated circuit capable of producing high quality sine, square, triangle, ramp, and pulse waveforms. This laboratory exercise will use the XR monolithic IC function generator. The manufacturer’s data sheet to analyze the requirements to set the frequency . 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.

A common function generator provides sine, for example, triangular and square waves. The frequency is set by a capacitor, in the range 0. Use a buffered potentiometer to test the dependence of frequency on VC.
With the component values shown above, the overlapping frequency ranges are shown in the following table: The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same.
All required circuit details are shown in the datasheet.
You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.
Function Generator with XR With the frequency-determining capacitor of 0. 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.
Function Generator with XR2206
It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. Modulating the frequency with an external signal has quite a few applications. With datasheeet pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to and may include a range of 10 Hz to 20 kHz sweep. I found 10k and 0.
Arduino – XR Function Generator
The output was centered on 6. If the applied voltage V is 3. The sample design renounces everything that is not absolutely necessary. There are actually two timing resistors, and which one is used is selected by the level on pin 9.
Although neither chip is in current production, both are still widely available – either as datahseet stock or, perhaps, as ‘clones’. 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. The XR makes a quite passable sine wave. Frequency can be varied by a range switch and a potentiometer, so that one could make a fairly useful function generator based on this chip, at low cost.
For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. Instead of the sine wave output is obtained after opening of S1 a triangular output wave.
XR2206 Function Generator
A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked ratasheet at the pin 2. The output can be buffered to adjust its DC component and signal amplitude. The additional output at pin 11 also delivers a square wave with the same frequency. Many attempts xr206 come out with this simple circuit. At pin 3 to set the exact medium voltage and the output amplitude. In any case, do not exceed 3 mA from pin 7 or 8.
The proper adjustment of these controls is necessary for a good-looking sine dztasheet. The capacitor C and the power to determine the frequency at pin 7.
Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.
