how to generate an analog signal
Hello,
I am trying to build a circuit that can output a 0-5V analog signal.
This analog signal will be controlled by a mcu.
What i have in mind is to have a mcu communicate to some sort of 12bit dac.
I am familiar with the mcu portion of things, but i am not familiar with dac.
The 0-5V as a control signal to control an old power supply.
These are some of the questions i have:
1) Is there any cheap dac that anyone can recommend.
2) Typically do we use the dac to output the 0-5V signal directly or do we have to use some sort of buffer to scale the output of the dac to max at 5V and provide some current drive to drive connected circuit.
3) Can the entire dac/driver circuit be powered from a signal real supply?
4) Is there any other alternative?
Appreciate any feedback and help.
Cheers,
kupper
