variable voltage source
Hi
I need to build a variable voltage source that can deliver up to 1A current.
The voltage should be able to vary between 0V and 5V and it will be driven with a DAC.
The DAC can output up to 5V, but can't give a lot of current, so it will be connected to an OP-AMP.
I've heard of a design using a transistor and an OP-AMP, but it's not the one where you drive the transisor with the OP-AMP output.
Can someone please help me out?
PS: I'm working with high precision
