Default TA2024 output noise?

Just wondering if anyone has put a scope on the outputs of one of these to see how much switchig noise is present with no input,

Thanks

i would imagine doing the measurement with the chip powered from a battery would be the best way to go, no need to colour the result by adding power supply noise to it.

that and doing it over several of these chips inorder to average the result.

come to think of it is the figure in the datasheet?

Hi, I'm not asking how to perform the measurement. Powering it from a battery isn't going to change or decrease the switching noise on the output, yes it would eliminate the power supply added noise, thanks.
