I have a question regarding decoupling of AD8000 but it's a general question.
Can I place decoupling capacitors close to the GND (or -VS) pins instead of +Vs. I assume that results will be the same but I didn't find any article or note which speaks about that. Could you share experience or recommendations about that.
The goal is to choose during layout to put capacitors near pin +VS or -VS.
Hi,High frequency noise can occur on either of the supply rails of the amplifier. Decoupling only the -Vs means leaving the other supply pin susceptible to noise. Remember that the supply pins have different PSRR characteristic/performance, this is why it is always best to decouple both.Here are some articles regarding bypassing/decoupling supply pins:MT-101 Decoupling TechniquesIn and Out - or - Why have a Capacitor?
