Question

when an op-amp is operated in the single - ended differential mode,
select one:
○ a. both inputs are connected together
○ b. both inputs are grounded
○ c. the output is grounded
○ d. one input is grounded and the signal is applied to the other input

Explanation:

Single-ended differential mode for an op-amp is defined by applying an input signal to one terminal while grounding the other terminal, which matches option d. Options a, b, and c describe configurations that do not fit this operating mode.

Answer:

d. one input is grounded and the signal is applied to the other input
