Explanation: High voltage gain causes comparator output voltage to switch between saturation levels. High CMRR rejects noise at input terminal and input offset (voltage & current) help to keep changes in temperature variation very slight. 6. How to keep the output voltage swing of the op-amp comparator within specific limits?
A. External resistors or diodes are used
B. External zeners or diodes are used
C. External capacitors or diodes are used
D. External inductors or diodes are used
Answer:A

How to keep the output voltage swing of the op-amp comparator within specific limits?
A. External resistors or diodes are used B. External zeners or diodes are used C. External capacitors or diodes are used D. External inductors or diodes are used
Explanation: To keep the output voltage swing within specific limit, op-amps are used with external wired components such as zeners or diodes. In the resulting circuit, the outputs are limited to predetermined values. 7. Zero crossing detectors is also called as
