Question

identify the type of input mode for the op amp
select one:
○ a. dual ended differential mode
○ b. common mode
○ c. single ended differential mode

Explanation:

In this configuration, two distinct input signals ($V_{in1}$ and $V_{in2}$) are applied to the inverting and non-inverting terminals of the op-amp respectively, with neither input grounded relative to the other. This matches the definition of dual ended differential mode, where the op-amp responds to the difference between the two independent input signals.

Answer:

a. Dual ended differential mode
