ICL8038 signal gen

The frequency meter has been used in this construction, so its completes the whole generator and kcl8038 to perform the frequency adjust without using an external meter or oscilloscope.

Graphics in attachment shows the connections of switches, in this case, I used two rotating ones, 2 x 6 rows each.

ICL chip changes its oscillation frequency depending on the temperature, so when ic,8038 turn on the generator, wait approximately two minutes until all the elements get heated to they operating temperature and then fine-tune the frequency. The two ICL chips that i have can oscillate around up to kHz, and practically we can get good waveforms up to that frequency.

Shielding, temperature drift Whole electronic circuit is protected by a tin to minimize the impact of the electromagnetic field of a transformer and power lines. Here, i fixed the square wave with a comparator so that the slope is pretty steep, steep as applied comparator can give. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.

After stabilize, the frequency can change a bit ICL chip faultbut it should not change over time.

For example, a cold circuit set to kHz, decreases its frequency by about kHz after warming up. 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 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. Its marked as 10uF bipolar on the schematic, but its good to put icl0838 one to reduce this effect.

Imperfections In this article i described how to make a simple front panel its not translated, sorryand beside regular files such as PCB files, i added a ready-to-print design of the front panel in the PDF format, suitable for housing Z1A, in the attachment.

This signal is fed to the meter, the AVR input pin accepts such signals. Here, the potentiometer is used as a source of compare voltage for the comparator, set it to get the same signal duty that has been set for ICL.

Square output pin 9 with open collector, normally would never be able to give a good square wave at these frequencies. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. Voltage transformer should have a 2x14V minimum to allow the proper operation of and stabilizers.

As it turned out its only making them worse, and add a characteristic spout on the top of the upper half of the sine.

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. Rising edge depends only on the pull-up resistor and its growing very slowly. In some way the quality of other waveforms is dependent on the load on this pin. It also analyzes transistor’s characteristics such as voltage and gain. If we give too strong pull-up resistor, in turn, the icl838 edge will be weak because the internal transistor is too heavily loaded.

I got rid of some of the elements, I added my own solutions. Additionally In my version of device i added the input mode for the meter, which can be selected on the range switch, and the output connector can be used to measure external signals. Amplitude and DC offset adjustment Waveforms obtained in this way still need to be fed to the operational amplifier that will allow setting of the amplitude and DC offset.

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. Sinusoidal and triangular waveforms will be passed nice, but we can forget about the square. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

Sinusoidal signal coming from the ICL is 5. Since the input voltage for the comparator has a greater amplitude than its supply voltage, I decided to fed it just trough the current limiting resistor.

Offset, amplitude, and frequency scales are pretty icl808. The signal may be larger, it is matched by the same elements that adjust it at the output of the comparator. I found a workaround by not putting the load on the square wave output from pin 9 open collector that needs to be pulled up to the power supply.

Shown in the schematic LM 1. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting ic,8038 sensors and connectors. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
