I'm looking for a dual OPAMP which has output shutdown function with less than 1mV(Max) offset voltage. The AD8647 is one of my candidate but offset voltage is 2.5mV(max). When I search an opamp, I noticed offset voltage of most of opamp with shudwon/power-down function is "mV" order. Is there any low Vos opamp with shutdown function?
Aside from being a dual amp with shutdown function and a max Vos<1mV, could you provide other specification that you are most concerned of? I'm looking at AD8028, ADA4897-2, and ADA4895-2 could be used in your application.
I hope this helps.
Thank you for reply and suggestion.
The ADA4897-2 is already evaluated but there was signal leakage from input to output when power-down was enabled. So AD8028 might be good.
