    on the 741 OpAmp

    Thanks steve. Just please inform on how I can ensure a STABLE POSITIVE voltage at the output

    on the 741 OpAmp

    Hello All. I know that the output (amplified) of a practical amplifier cannot go beyind that of its power supply. I need to know if an input of 12V to a 741 with a supply voltage of 5V will damage the opAmp or if I will just get my 5V out without any trouble. I have a circuit in which the input...

    Low voltage Relay

    Hi poor mystic. Thank you. I got much more convenient solution. I will amplify the voltage using an opAmp and use the amplified voltage to trigger a Solid State relay. The relays control voltage is 3-10V and its acceptable load parameters are 0-100V, 10A max. This is just perfect for my case...

    In Rush Current Limiter

    Just any fuse? Will I not need a DC fuse...? Can you reccomend from RS or farnell or any of the major providers? Thanks!

    In Rush Current Limiter

    Oh, sorry I mean current, not voltage. In short, steve, how do I protect my DC system, running a nominal current of 7A, from a short circuit?

    In Rush Current Limiter

    The load should not draw more than 7A. I agree that I should use a fuse, and hence would like to know if there are special fuses for DC in this case. The spec should be a 7A trip voltage and it should operate at 12V. Please take note that it will be on a PCB so size is a very big issue. Thanks.

    In Rush Current Limiter

    Can I use an in-rush Current Limiter in a DC circuit? I have a 12V car battery and i dont want the current to the load to go beyond 7A. I have a 7A current limiter from Ametherm available. Is this possible? If not, what alternative doi I have?

    Low voltage Relay

    Hello all. I am working on an circuit in which I require a switch to arm if the voltage between the terminals of the load is less than -200mV (e.g, switch is armed if V=-400mV but disarms if V=-100mV) so that I can send current to the load from a battery source. I am thinking that a relay with...
