The output frequency can be modulated by an external voltage using the circuit shown at the right.

One could make a small AM radio transmitter with this chip for use over short distances. It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

The 50k pot adjustment is also important. The capacitor C and the power to determine the frequency at pin 7.

Less than 30ns at 1kHz Symmetry: This circuit sets the average value of the output waveform here to 6. The additional output at pin 11 also delivers a square wave with the same frequency. The chip is advertised to work down to 0. But there are some points that could improve it take to build an almost professional function generator.


The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

It can produce a triangle wave, but this is really just a step towards the sine wave, xd2206 is seldom required. An increase in V lowers the frequency, and an increase raises it.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all iv of RF coils and inductors. With a 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. There are actually two timing resistors, and which one is used is selected by the level on pin 9.

If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both.

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. The XR has some interesting features that illustrate some of the topics mentioned dr2206 this page, so let’s examine this chip. The output waveforms can be both amplitude and frequency modulated. R is the normal timing resisor, while RC handles the i current. It requires an operating voltage of 12 V and delivers sine and square wave signals.

One is displaying frequency response on the scope–you might try this with a parallel resonant circuit. 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.


The actual sample structure differs in some id from the data sheet. The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. When pin 9 is open or above 2 V, the resistor called R1 is used.

Headphone amplifier is small enough to fit in Altoids tin box, and thanks xr22206 low power consumption may be supplied from a single 9V battery. The output waveforms can be both amplitude and frequency modulated. 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.

All required circuit details are xr206 in the datasheet. The XR has an AM input at pin 1. At pin 3 to set the exact medium voltage and the output amplitude.

The proper adjustment of these controls is necessary for a good-looking sine wave. A common function generator provides xr206, for example, triangular and square waves.

XR data sheet provides complete basic circuit for a simple function generator. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz.
