[Moved] maximum output current measurement

[shinulalu6]

hi
As you said we need to keep the opamp in voltage follower configuration and keep varying the resistive load until the voltage drops.

what in the case of capacitive load,what should we do here in order to measure the output current?

See https://www.edaboard.com/threads/266157/ for reference

The type of load doesn't matter, so checking for the maximum op amp output current with a resistive load will also tell you the maximum current it can deliver into a capacitive load.

hello i have a doubt............

when my load is capacitive,will i able to measure to the maximum output current replacing resistive load.

bcz in my op-amp, open loop output impedance is high,so it is not able to drive the resistive load.


so will i get the maximum output current by keeping resistive load instead of CL....
