Exar Xr2206cp Monolithic Function Generator DIP IC XR2206
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.
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 circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
The proper adjustment of these controls is necessary for a good-looking sine wave. A circuit for testing the XR is shown at the right. The output can be buffered to adjust its DC component and signal amplitude. The XR provides a square wave at an open-collector output, as well as a sine wave. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. The kit includes output that can be connected to our 60MHz Counter kit to measure output frequency.
Function Generator is an essential laboratory equipment. The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. The output waveforms can be both amplitude and frequency modulated. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. It also analyzes transistor’s characteristics such as voltage and gain. Use a buffered potentiometer to test the dependence of frequency on VC.
Less than 30ns at 1kHz Symmetry: 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. There are integrated circuits that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle wave.
XR Function Generator
A common function generator provides sine, for example, triangular and square waves. Many attempts have come out with this simple circuit. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types xr2206 RF coils and inductors.
Supply VC from a function generator, setting the DC bias at 3. This circuit sets the average value of the output waveform here to 6.
This gives easy frequency-shift keying FSK by a logic input to pin 9.
Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The output was centered on 6. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. I simply put the end of the whip antenna of the small pocket radio near the output of the XR, and got plenty of signal. Xr2206 also analyzes transistor’s characteristics such as voltage and gain.
Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit. Frequency can be varied by a range switch and a potentiometer, so that one could make a xg2206 useful function generator based on this chip, at low cost. I used modulation at 1. The DC bias at this input is necessary, and the signal amplitude must xr220 properly adjusted.

The waveform looks like a spring extending and contracting! Frequency output can be fine tuned using P1 and P2 potentiometers. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. 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. It can produce a triangle wave, but this is really just a step towards the sine wave, and is seldom required.

The actual sample structure differs in some details from the data sheet. The 50k pot adjustment is also important. An increase in V lowers the frequency, and an increase raises it. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. At pin 3 to set the exact medium voltage and the output amplitude.
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. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
One could make a small AM radio transmitter with this chip for use over short distances. 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 xxr2206, crystals, etc.
If the applied voltage V is 3. XR data sheet provides complete basic circuit for a simple function generator. But there are some points that could improve it take to build an almost professional function generator. Instead of the sine wave output is obtained after opening of S1 a triangular output wave. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
