Function Generator with XR2206

For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms. A common function generator provides sine, for example, triangular and square waves. The frequency must be adjustable and at least cover the low frequency range. The low-cost IC XR provides a very simple function generator with only a dwtasheet external components.

XR data sheet provides complete basic circuit for a simple function generator. It requires an operating voltage of 12 V and delivers sine and square wave signals. Instead of the sine wave output is obtained after opening of S1 a triangular output wave. The capacitor C and the power to determine the frequency at pin 7. 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 daasheet Hz dtaasheet 20 kHz sweep.

A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. At pin 3 to set the exact medium voltage and the output amplitude. The additional output at pin 11 also delivers a square wave with the same frequency.


The actual sample structure differs in some details from the data sheet. Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible.

XR2206 Function Generator

With the frequency-determining capacitor of 0. The frequency is changed by using a variable resistor. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. 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 sample design renounces everything that is not absolutely necessary.

Many ci have come out with this simple circuit. But there are some points that could improve it take to build an almost professional function generator.

All required circuit datsheet are shown in the datasheet. Switching frequency ranges from about xrr 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. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. The output waveforms can be both amplitude and frequency modulated.

Function Generator with XR The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. 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, eatasheet, function generators, crystals, etc.


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.

It also analyzes transistor’s characteristics dstasheet as voltage and gain.

It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Headphone amplifier is small enough to fit in Altoids tin box, and thanks to low power cr may be supplied from a single 9V battery.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors dayasheet connectors. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. 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.
