can we apply +ve and -ve voltages to a comparator if we operate it with single supply
I am haivng a doubt on using LF356/general op-Amp as a comparator.
I do believe that LF356 Op amp can be operated with dual mode supply +12v and -12V and single mode supply.suppose if I am operating the op...
Sir,
In my circuit I have used op amps (LF356) as Amplifier, subractor and buffer and LF398 as sample and hold amplifier. After processing the input signal the output is taken at the last stage of the LF356 amplifier. As the input signal is in millivolts it is amplified and process with a small...
Hai,
I request you kindly go through the mail attachment also.
I want to amplify a signal transient which does not have a symmetrical shape (e.g. shapes like sine or square e.t.c) and certain portion of that transient varies with temperature sweep. The maximum and minimum amplitude...
Thanks for your reply. suppose If I have a +12V and -12V voltage sources and I do want to have a variable voltage source variable between +5V to -5V DC. How can I achieve it. Is there need to have 7805 7905 voltage regulators again at the o/p of 12V and -12V Dc for having a single variable +5 to...
Hello,
I have a three channel power supply, +5V, +12V, -12V DC regulated developed using LM317 and LM337 ICs. Now I want to have a voltage source that can be varied between +12V to -12V DC. This variable voltage is used for reference/offset adjustment of the comparator circuit.
Kindly help me...
Hello
Thanks for your reply. I found the potential difference and analog ground is 20 mv. Is there necessary to make it near to zero millivolts difference between them.
Re: How to connect the grounds as STAR GROUND and How to cross check them?
kindly let me know resistance between grounds before and after switching the power supply on. Will the resistance between the grounds vary.
How to connect the grounds as STAR GROUND and How to cross check them?
Hai,
I am little bit confused about the routing/wiring to form a star ground.
I have a designed a signal averager (box car averager) circuit with few digital ICs (10 numbers) 74ls00, 74ls04, 74ls244, 74ls393 and analog...
Hai,
I am using opamp LF356 as high gain amplifier with gain upto 1000 with +16 and -16 volts as powersupply to the IC.
I want to amplify the input DC transient of voltage 10mv to 100mv maximum. When the gain is changed from 1 to 1000, I found the signal in CRO is total distorted. At Gain of 1...
