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 output can be buffered to adjust its DC component and signal amplitude. Although this is an analogue IC, this project just made it into the Arduino section of my website because it uses an ATmega as a frequency counter and to drive an 8-digit 0.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. It also analyzes transistor’s characteristics such as voltage and gain. The frequency is changed by using a variable resistor. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.

Arduino – XR Function Generator

The proper adjustment of these controls is necessary for a good-looking sine wave. When pin 9 is open or above 2 V, the resistor called R1 is used. The frequency is set by a capacitor, in the range 0. The output waveforms can be both amplitude and frequency modulated. I used modulation at 1.

Function Generator with XR But there are some points that could improve it take to build an almost professional function generator. One could make a small AM radio transmitter with this chip for use over short distances.

A common function generator provides sine, for example, triangular and square waves.

The output frequency datsheet be modulated by an external voltage using the circuit shown at the right. There are actually two timing resistors, and which one is used is selected by the level on pin 9. This gives easy frequency-shift keying FSK by a logic input to pin 9. The output waveforms can be both amplitude and frequency modulated. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same.

XR2206 Function Generator

On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with datasjeet clips. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. It can produce a triangle wave, but this is really just a step towards the sine wave, and is seldom required.

Thus, only dtasheet frequency ratio of 1 was chosen toso a finer adjustment is possible.

Function Generator with XR2206

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. A circuit for testing the XR is shown at the right. When pin 9 is below 0. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz. It requires an operating voltage of 12 V and delivers sine and square wave signals.

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 pin 7 and v. You can dztasheet 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. Frequency dataxheet 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.

The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard.

Instead of the sine wave output is obtained after opening of S1 a triangular output wave. The overlapping of the ranges isn’t ideal but it hasn’t proven to be a problem in practice. Modulating datashet frequency with an external signal has quite a few applications.

FM would also be good for testing a phase-locked loop. The XR provides a square wave at an open-collector output, as well as a sine wave.

The sample design renounces everything that is not absolutely necessary. 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 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. R is the datasheeet timing resisor, while RC handles the modulating current. At pin 3 to set the exact medium voltage and the output amplitude.

The formula for the frequency is shown in the figure.
