LP8556: LOOP GAIN measuremnt

Antony Lin

Part Number: LP8556

Hi,

Customer would like to measure the loop gain of LP8556 based on the diagram shown below. Do they place the 10ohm resistor at the right location? If not, what is the correct way? Thanks!

Hi Antony,

This method has no problem. BTW, as a friendly reminder, customer should select proper resister to match frequency analyzer output impedance. For example, 50 Ohm is the required resister for AP300.
