I'm confused. Post the schematic.Hi Everybody,
Does anybody have the equations for the circuit from Ron H
Many thanks
Are you wanting a general procedure for designing a level shifter? There are several variables involved, such asMany thanks Ron,
That's the one, i added the above question to the original thread and someone kindly started a new one for me.
Last time i had a problem like this was around 15 years ago and i've been racking my memory about how i did it . It was in a book in my office at the time that belonged to someone else, i still know where that book is (can't remember title or author ) but can't get access to it anymore. I did copy the section but thats around here somewhere and is alluding every search.
The example link given by Jony130 ( many thanks Jony130 ) is close. In his example he sets vd to the lowest of the input voltages. In your example you don't seem to do that, the Vout starts at 13v when R2 is tied to 15v. If i remember rightly it means setting the inverting and non-inverting equations equal to one another and going from there. Could anyone clear up my confused understanding.
Many thanks
Mr Smiley
