Hello 

We need a new and low-cost alternative from TI for the below-mentioned analog device part number ( AD8628WAEZ-RL) for automotive LV current sensing application. Zero drift opamp would be best.

    hello Charles

    Are you using the quad? AD8630. If so, then I would recommend the OPA4376-Q1. It is not a Zero Drift device but it is trimmed and offers very good DC performance. As far as choppers, we have the OPA2317-Q1 as low cost solution (dual) and the soon to be released OPA2388-Q1. We also have a plan for the quad OPA4388 in Q1. 

    Let me know which of these is most interesting to you.

    Currently we are using Quad IC of which 2 are used as voltage followers/buffers. We are looking forward to OPA2388-Q1 or OPA4388-Q1. Can you tell a tentative date of release and approximate price for 1k quantity for these two parts.

    We are targeting the dual by the end of the year and the quad in the first quarter (tentatively). 

    The 1k price should be around $1.5 and slightly above $2 for the dual and quad respectively. 

    My email address is Soufiane.Bendaoud@ti.com, let me know if you need samples so I can set some aside for you.
