Built this cct yesterday and it works really well. The formulae to calculate the set oscillator frequency is shown below; typically the value is set to 48 kHz.

Then a known reference voltage of opposite polarity is applied to the input of the integrator and allowed to ramp until the output of integrator becomes zero. Resubmit your request using a business or educational e-mail address registered with Maxim Contact your Maxim distributor Thank you for your interest in Maxim.
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. Capacitor C2 neutralizes the fluctuations in the internal reference voltage and increases the stability of the display. The power dissipation is less than 10mW and the display stability is very high. R4 controls the range of the voltmeter.
The ADC used here is a dual slop ADC, so the applied voltage is compared with a reference voltage and then is approximated to find the applied voltage. 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.
Finally, the true economy of single power supply operation ICLenables a high performance panel meter to be built with the addition of only 10 passive components and a display. Assemble Components and Test the circuit 1. Somebody pls tell me… Does the tolerance of the capacitors used matter??
Prices are in U.
For switching ranges used 4 pole 3 way rotary switch, first pole changes resistor and second pole moves decimal point pin 5 on indicator from D1 ucl7107 v DC to D3 ie v DC.
It also analyzes transistor's characteristics such as voltage and gain. What project s will these Maxim parts be used in? The ICL is a high performance, low power, 3. Then adjust R6 so that the display reads 0V.

For volume-specific and version-specific prices and delivery, please see the price and availability page or contact an authorized distributor. Assemble the circuit on a good quality PCB. Hello A similar project is available with PCB and the works, do check the same. Top menu About Us Advertise. Finally, the true economy of single power supply operation ICLenables a high performance panel meter to be built with the addition of only 10 passive components and a display.
This information is provided on the Renesas website provided for convenience and informational purposes only. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
In the above circuit the maximum reading can be The true differential input and reference are particularly useful when making ratiometric measurements ohms or bridge transducers.
For calibration, power up the circuit and short the input terminals. Embedded Security Security Managers. All Categories Recent Searches. I completly removed R4, but it is not working linearely… Anybody tryed to use the V range?
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. Comment if you have any questions. Modify it to accept 0 to 1.
The accuracy and the range of the measured voltage can be measured by using external circuits involving potential divider or op-amps but as always there is a trade off between the accuracy and range.
