The XR has some interesting features that illustrate some of the topics mentioned in this page, so let’s examine this chip.

XR2206 Function Generator

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.

All required circuit details are xr2260 in the datasheet. Frequency dagasheet 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 applied voltage V is 3.

The chip is advertised to work down to 0. The additional output at pin 11 also delivers a square wave with the same frequency.

The output can be buffered to adjust its DC component and signal amplitude. It is a very useful bench test equipment for testing and icc out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. The frequency must be adjustable and at least cover the low frequency range.

Function Generator with XR

A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2. 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.

The frequency is changed by using a variable resistor. 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.

Arduino – XR Function Generator

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. I simply put the end of the whip antenna ci the small pocket radio near the output of the XR, and got plenty of signal.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. Function Generator with XR It can produce a triangle wave, but this is really just a step towards the sine wave, and is seldom required. The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency. 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 output was centered on 6. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and iv must be monitored.

One could make a small AM radio transmitter with this chip for use over short distances. It requires an operating voltage of 12 V and delivers sine and square wave signals. An increase in V lowers the frequency, and datasheer increase raises it.

The proper adjustment of these controls is necessary for a good-looking sine wave.

Datashdet sample design renounces everything that is not absolutely necessary. The output frequency can be modulated by an external voltage using the circuit shown at the right.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and datsaheet. The actual sample structure differs in some details from the data sheet.

The frequency is set by a capacitor, in the range 0. Reducing R to 2k gave an ideal 20 ms period, or 50 Hz.
