Op Amp as COMPARATOR
In the circuit below, the non-inverting
input is connected to "ground", so V+=0.
Use the +7·2v 0 -7·2v rechargeable battery packs made
specially for op amp experiments.
Vary the voltage applied to the inverting input (using the variable potential divider) to show that:
|
and if |
V- > 0 then |
Vo = ____________ |
|
and if |
V- < 0 then |
Vo = ____________ |
Repeat the experiment with the INVERTING input connected to ground and the non-inverting input
connected to the variable potential divider. Now we find:
|
and if |
V+ > 0 then |
Vo = ____________ |
|
and if |
V+ < 0 then |
Vo = ____________ |
