How would I construct a circuit similar to a differential op amp but I ALWAYS want the output to be positive.
So for example V1=non-inverting pin and V=inverting pin
When V1 is 1.5V and V2 is 3V I want Vout to be 1.5V
Then if V1 is 3V and V2 is 1.5V I want Vout to still be 1.5V
So for example V1=non-inverting pin and V=inverting pin
When V1 is 1.5V and V2 is 3V I want Vout to be 1.5V
Then if V1 is 3V and V2 is 1.5V I want Vout to still be 1.5V
