I'm looking for an op-amp circuit to amplify a TTL signal from 0-3.3v ( Micro-controller operating voltage ) up to 0-10v range. Some explanation on how a circuit like this works would be useful as well
I assume to drive a Mosfet transistor? Please clarify what the 10V will be used for and current requirements. Switching speed info is also helpful. What is supply voltage to bring up to 10VI'm looking for an op-amp circuit to amplify a TTL signal from 0-3.3v ( Micro-controller operating voltage ) up to 0-10v range.

In my senior design project we used automotive fan, like the one under the hood of your car. It used 0 to 10 VDC signal to control fan speed. Our micro (Arduino Due) had (on paper) DAC that was 0 to 3.3 VDC (in reality it was 0.5 to 2.7 VDC). My guess is that OP has similar situation.I assume to drive a Mosfet transistor?

Just pick any op amp that is single source (that way you use one power supply to power the op amp) and rail to rail. You will have 4 parts: one op amp, two resistors, one power supply.It is the same sort of situation, i've found several designs on internet and they don't conclude a clear way to solve issues like this, unfortunately
The output is inverted. They will need a second transistor/op amp to invert a second time.
I am exactly having the same problem and i was finding solution for this on Internet & came across this thread. Can you please tell me, Have you been able to find a correct solution. I have also tried implementing the 2-stage CE amplifier solution, but, there seems quite a heat dissipation across the collector resistor. Can someone help & throw more light on the same?I'm looking for an op-amp circuit to amplify a TTL signal from 0-3.3v ( Micro-controller operating voltage ) up to 0-10v range.
