LME49710 Capacitive Loading

Mark Amarandos

AN-1651 shows an application circuit for the LME49710 with a 1uF load capacitor. Does that circuit work as shown or is there something missing? A series resistor perhaps?

Hi, Mark,

Welcome to e2e, and thanks for your interest in our products.

That seems strange to me as well. Unfortunately, the author is no longer with NSC/TI, so I do not have any further information.

I built up that circuit on a crappy little proto board and it worked as advertised. Even with another 1 uF of load capacitance it was stable. That is one stout little amplifier and quiet as a mouse.
