10uF on output of an operation amplifer

[doofus32]

I am going to have an stable voltage reference point, that have a low impendans.
Is there any problem to connect an 10uF cap to ground on the output of an operation amplifer?

On turn on power, can it go a lot of current to the cap, so the operation amplifer gets damaged?

Connecting a 10µF cap on the opamp's output is not a good idea ..

Opamps have very low output impedance so connecting caps there won't be effective ..

Instead, try to connect a cap on the opamp's (+) input ..

A 10 uF capacitor connected to your Op-Amp O/P may destroy the O/P stage of the Amplifier, because at power on, a capacitor is supposed to act as a voltage sink, i.e., an instantaneous short circuit will be applied to your Op-Amp O/P pin, The capacitor voltage will increase gradually as it's charging from the O/P pin.

Try to Avoid this approach.

Isn't capacitive load on the OP-amp a way to get OP-amp unstable? However one can avoid this using some RC network to the inputs...

it won't nescessary burn the opamp, most of them are protected from short-circuit, but it can surely get it unstable.
If you think that you need the cap at the output, connect it with a small resistor in series.

Some opamps are stable when driving a large capacitive load. Check the data sheet - this feature is usually highlighted on the first page.
