Topic: easiest way of driving amplifying from 5v to 12v (Read 6169 times) previous topic - next topic

Why not use a proper mosfet driver IC such as TC4420 or TC4429? These will convert a logic signal from 5v to 12V and have good output drive in both directions.

Now that is perfect, exactly what im looking for in terms of size and functionality as well as simplicity
thank you

Well, if you're going to go shopping then why not get a logic-level FET?
How much current is the FET supposed to switch, anyway?
At first I thought this was about Arduino and using some IRF-type FETs you had on hand.
Then it turns out it was an about an op-amp (comparator).

I am shopping around still, there is a 328p involved but its too busy to do the job of the comparator, I already decided on the mosfets for this project and bought those,(4 for an hbridge and one to turn the whole thing off entirely separate )
its more for incorporating into the design for my much larger project, I just was interested in finding the best wayfor my needs, I have 5v and 12v readily accessible I just didn't know the best(simplest) way to do it, using a dedicated driver that can be controlled from logic makes sense I just didn't think of even looking for something like that, I was first thinking of a non discrete way, but this definetly fits perfect

If the signal to be amplified is AC only, then a transformer is a simple way to level shift, but won't give power-amplification.
