[sdiy] Generating +5V gate signals from +3.3V logic

[Tom Wiltshire]

Hi All,

Subject says it all really.

I'm running a 3.3V dsPIC and I want to generate 0-5V gate outputs from it. I've got a 3.3V supply for the uP, and a +/-12V for the op-amps, but no +5V supply.

Is there a simple way to get a 0-5V output without having to add a +5V supply?

Obviously if I have the +5V supply I could use some logic convertor chip, but I'd like to avoid another supply for one single chip if possible.

Thanks,
Tom
