*Non-linear application
is where the op-amp operate in linear region
Linear application
Assumptions in linear application:
- Input current, Ii = 0
- Input voltage: V+=V-
- Feedback at the inverting input
readings
is where the op-amp operate in non-linear region
Non-linear application
By comparing these two input voltages: positive input voltages, V+ and negative input voltage, V- where:
VO = VCC if V+ > V-
VO = -VEE if V+ < V-
*Input current, Ii = 0
readings
Provide a constant gain multiplier
