This application note explains how to measure the closed-loop transfer function and bandwidth of a single-supply operational amplifier (Op-Amp) in a non-inverting configuration.

It examines multiple gain settings to evaluate how gain affects amplifier performance.
The measurements provide practical verification of real-world behavior beyond the specific conditions shown in datasheet gain-bandwidth plots.
