Thank you so much guyz
my problem is sloved now
i am using ICL7662 it gives me -11.7V pprox with the input of 12V.
and ICL7660 can also be used for the same purpose
:wink::smile:
Just try it jVenky
From a single battery,take 4 terminals out.Two positive and two negative then for 12V ground negative terminal and for -12 V ground positive then u will suddenly realize that u have shorted your battery.
Secondly if it is so simple then why many companies are providing...
i am using LM339 amplifier as a comprator.The input signal (0-5V rectangular wave) will be changed in 12V to -12V.For the Vcc i have 12V but for -Vcc i don't have -12V as i am using single power supply.So i am suppose to find a chip which converts 12 volts to -12V.The current drawn by all...
guyz
i have a 12-12.6V dc input and i need such chip which gives me -12v dc as a output.
Initially i search lm7912 for this purpose and then i came to know that it needs also negative input(correct me if i am wrong please as i am not crystal clear about it)
so can u suggest some chips to...
I am using TL082 amplifier to get the gain of 10.Input of circuit is 10mV(10m to -10m) sine wave but the output i get is 50m to -150m.My output is shifted(50mv down).
Can anybody tell me the reason.
Schematics and output are given below.I m using non inverting configuration of op amp.Will...
I am working on a ultrasonic sensor for distance estimation(level of fuel) in a tank(fuel tank of car).I have to generate a burst of 10 pulses (0-5v) then i need an input of -10-10v for a ultrasonic sensor to transmit ultrasonic pulse.I have to work with 12 v DC(car's battery).
I think i have to...
