Video Amps And Modules FAQ

How does the LT6552 handle capacitive loads?

The datasheet notes that driving loads greater than 10mA may require additional bypass capacitance. Stability with capacitive loads can be managed using series output resistors or feedback capacitors to prevent peaking.

What is the effect of closed-loop gain on performance?

The LT6552 is optimized for closed-loop gains of 2 or greater. Lower gains may result in frequency response peaking, which can be mitigated by adjusting feedback resistor values or adding a capacitor across the feedback resistor.
