Hi there,

 

I have an question.

I consider using an external cap for ADM2582 board layout.

But I just wondered where the external capacitor should be placed?
Accodring to Fig 26 on AN-0971,Looks like it’s connected between the PWR and GND pattern.

See  the graph and the following URL.
http://www.analog.com/static/imported-files/application_notes/AN-0971.pdf

I thought it should be placed between GND and GND like  Stitching Capacitance  effect.

Please give me some advice on that.

 

Best regards,

Tarzan
