Open op amps
Can be used as a boolean comparator
-
Can turn analog signals
- where you have a reference voltage in one input and the analog signal in the other and depending if its inverting we can make it a digital signal
- we can connect the ref to ground to make it detect if it crosses 0 feed back
Op Amps feed back
- Ve feed back
-
Brings the opamp to stability
-
it produces a phenomenon called “virtual short”
- this is = to a short between +- inputs
