Zero Drift, Low offset opamp- current sensing-automotive -AD8630WARZ-RL-Alternate

Other Parts Discussed in Thread: OPA2388-Q1, OPA4376-Q1, OPA4388, OPA2317-Q1, OPA4388-Q1


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. 

  • Charles

    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, let me know if you need samples so I can set some aside for you.
