Instead of the sine wave output is obtained after opening of S1 a triangular output wave.

XR Function Generator

With the frequency-determining capacitor of 0. For this project, I was more interested in producing a clean undistorted sinewave rather than iv it to the limits in terms of frequency.

It can produce a triangle wave, but this is really just a step towards the sine wave, and is seldom required. Supply VC from a function generator, setting the DC bias at 3. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.

Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both.

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 chip is advertised to work down to 0. The frequency is changed by using a variable resistor. When pin 9 is below 0.

The output waveforms can be both amplitude and frequency modulated.

The frequency must be adjustable and at least cover the low frequency range. In any case, do not exceed 3 mA from pin 7 or 8. The output was centered on 6. I found 10k and 0. The proper adjustment of these controls is necessary for a good-looking sine wave.

The XR has an AM input at pin 1. Use a buffered potentiometer to test the dependence of frequency on VC.

Function Generator with XR2206

The frequency is set by a capacitor, in the range 0. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. One could make a small AM radio transmitter with this chip for use over short distances. The waveform looks like a spring extending and contracting! 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.

With the component values shown above, the overlapping frequency ranges are shown in the following table: 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.

A circuit for testing the XR is shown at the right. It also analyzes transistor’s characteristics such as voltage and gain. All required circuit details are shown in the datasheet.

The 50k pot adjustment is also important. When pin 9 is open or above 2 V, the resistor called R1 is used. At pin iic to set the exact medium voltage and the output amplitude.

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.

If the applied voltage V is 3.

The actual sample structure differs in some details from the data sheet. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power consumption datashfet be supplied from a single 9V battery. A common function generator provides sine, for example, triangular and square waves. Pins 7 and 8 are held at 3 V, and more than 3 mA should not be drawn from them, so 1k is the minimum timing resistor.

The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

A sine-shaping network makes xt2206 triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. 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 datsheet 7 and v. It requires an operating voltage of 12 V and delivers sine and square wave signals.

Arduino Prototype uses all standard through-hole components for datadheet construction, two of which are hidden underneath IC socket. The output frequency can be modulated by an external voltage using the circuit shown at the right.

The XR has some interesting features uc illustrate some of the topics mentioned in this page, so let’s examine this chip.

R is the normal timing resisor, while RC handles the modulating current. It’s small, power efficient, yet customizable dataseet onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. The formula for the frequency is shown in the figure. XR data sheet provides complete basic circuit for a simple function generator. Function Generator with XR
