A common function generator provides sine, for example, triangular and square waves. At pin 3 to set the exact medium voltage and jc output amplitude. The frequency must be adjustable and at least cover the low frequency range. It also analyzes transistor’s characteristics such as voltage and gain. XR data sheet provides complete basic circuit for a simple function generator.
The kHz signal could be picked up on an AM radio at the expected frequency, and the modulation heard. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
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. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.
It requires an operating voltage of 12 V and delivers sine and square wave signals. 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. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
The output frequency can be modulated by an external voltage using the circuit shown at the right. The XR provides a square wave at an open-collector output, as well as a sine wave. R is the normal timing resisor, while RC handles the modulating current.
This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket.
The actual sample structure differs in some details from the data sheet. Headphone amplifier is small iic to fit in Altoids tin box, and thanks to low power consumption may datasheett supplied from a single 9V battery.
For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency.
The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.
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.
There are actually two timing resistors, and which one is used is selected by the level on pin 9. The sample design renounces everything that is not absolutely necessary. Although I’ve seen circuits and even commercial project kits claiming several MHz frequency range, in practice I think somewhere around kHz or kHz maximum frequency is more realistic for these ICs while still maintaining a reasonably low-distortion sine waveform.
The low-cost IC XR provides a very simple function generator with only a few external components. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types datashret RF coils and inductors.
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. The XR offers many possibilities for sine wave generation and modulation over a dwtasheet range of frequency. 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.
Although neither chip is in current production, both are still widely available – either as old stock or, perhaps, as ‘clones’.

Thus, only a frequency ratio of 1 was chosen toso a finer adjustment is possible. The chip is advertised to work down to 0. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize dtasheet of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit. On the board, the outputs of the circuit were placed in small wire loops, where dr2206 signals can be picked up directly with alligator clips.
Arduino – XR Function Generator
Supply VC from a function generator, setting the DC bias at 3. The frequency is set by a capacitor, satasheet the range 0. For measurement purposes in the electronics laboratory is needed again and again signals of different frequency and waveforms.
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 xatasheet you can think of.
Many attempts have come out with this simple circuit.
The formula for the frequency datssheet shown in the figure. One could make a small AM radio transmitter with this chip for use over short daatsheet. Modulating the frequency with an external signal has quite a few applications. With the frequency-determining capacitor of 0. The XR makes a quite passable sine wave. 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.
There are integrated dataheet that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle wave. The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit.
The proper adjustment of these controls is datashret for a good-looking sine wave. 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.
If the amplitude is not set correctly, the waveform will have flat tops or bottoms, or both.
