The waveform looks like a spring extending and contracting!

XR Datasheet(PDF) – Exar Corporation

The frequency is changed by using a variable resistor. It can produce fatasheet triangle wave, but this is really just a step towards the sine wave, and is seldom required. The chip is advertised to work down to 0. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz.

The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. 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. With a pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to datasheef may include a range of 10 Hz to 20 kHz sweep.

This circuit sets the average value of the output waveform here to 6. The output was centered on 6. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency.

The output waveforms can be both amplitude and frequency modulated. For x2r206 purposes in the electronics laboratory xd2206 needed again and again signals of different frequency and waveforms. When pin 9 is below 0. It also analyzes transistor’s characteristics such as voltage and gain.

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. The output can be buffered to adjust its DC component and signal amplitude. The frequency must be adjustable and at least cover the low frequency range. The frequency is set by a capacitor, in xr226 range 0.

XR data sheet provides complete basic circuit for a simple function generator. 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.

If the applied voltage V is 3. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

Instead of the sine wave output is obtained after opening of S1 a triangular output wave. 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. If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both.

An increase in V lowers the frequency, and an increase raises it. The 50k pot adjustment is also important. The low-cost IC XR provides a very simple function generator with only a few external components. You datasheett 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.

One could xatasheet a if AM radio transmitter with this chip for use over short distances.

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 But there are some points that could improve it take to build an almost professional function generator. The proper adjustment of these controls is necessary for a good-looking sine wave.

Function Generator with XR2206

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. It also analyzes transistor’s characteristics such as voltage and gain. Supply VC from a function generator, setting the DC bias at 3. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Dr2206 the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with alligator clips.

It requires an operating voltage of 12 V and delivers sine and square wave signals.

I found 10k and 0. 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. 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.
