4 cards from this section. Quick, good the night before a test.
What is the output of a comparator if the non-inverting input is greater than the inverting input?
Think about which input is larger.
What state does the output of a comparator assume when both inputs are equal?
Consider the situation when the voltages are the same.
What does a comparator output when the non-inverting input is greater than the inverting input?
Consider the rules of comparison.
True or False: A comparator's output is always equal to the average of its inputs.
Think about how comparators work.
You have a comparator with fixed reference voltage set at 2.5V. If the input voltage fluctuates between 1V to 3V, describe the output behavior when the input crosses the reference voltage.
Consider the point at which the input voltage transitions.
Design a comparator circuit that triggers an alert when the input voltage drops below a certain level. Explain the components needed and how they work together.
Think about how to connect the circuit to make it responsive.
