[sdiy] ...that 1K resistor on the output

[Justin Owen]

Hello,

Last week I was asking about passive vs. buffered multiples.

A few of you mentioned that you put a 1K resistor on the output of all op amps (or all outputs...) - can I ask: Is that in series i.e. between the output of the op-amp and the actual output or from the output of the op-amp to ground i.e. load?

And secondly - for AC-coupled outputs are you running op-amp > resistor > capacitor > output or op-amp > capacitor > resistor > output?

Thanks,

Justin
