OPA202: Product recommendation for less than 0.3mV Vos application

Hi team,

Background:

This is Divyanshu, applications for ORing controllers. We are building an application circuit to increase the operating voltage of one of our ORing controllers using precision op-amps to use as voltage buffers. The accuracy of our solution is directly affected by the inaccuracy introduced by the buffer because it is being used in the sense path. So we require a very high precision op-amp to use as a buffer. Also, we need a dual op-amp to reduce cost and effect of PVT variations on overall accuracy. 

The required specifications are- dual op-amp with less than 0.3mV offset voltage over output load variation between 1uA to 7mA and costs less than 0.5$. I was looking at OPA202 as a potential device which can be used. Kindly advise if there you have a better product recommendation. 

Thanks and best regards

Divyanshu
