Dear experts,
I am thinking of using an op amp to trigger a circuit.
The +ve input to the op amp should raise '1' (high) if the voltage is 5v and not anything less.
The -ve input to the op amp should always be '0' (low) and so i thin i short it to ground.
I wonder what op amp should i use, assuming just to achieve the above?
Am i right to say usually, op amps V+ raised to high when voltage is a few mV?
So, if my source is 5v, does it mean that i can achieve the objective by using a resistor as voltage divider to lower the V+ such that it is low enough to trigger a '1'?
Sincerely
Ramone
