OPA625: OPA625

Part Number: OPA625
Other Parts Discussed in Thread: OPA863, OPA810

Trying to use the BOM cross tool to match up to the ADA4807-1, it came back with only the OPA625 which looks about right AC wise, but

The ADA4807-1 is +/-5V capable, while the OPA625 is 5V max, got anything close that is in the+/-5V process cases?

This is kind of debiliitating to have only this one part BOM tool, the paramatric match tool with a range of options was more useful. 

  • Hello Michael,

      That is a good point. I can not seem to find the original amplifier cross reference tool; it seems to have been replaced with this BOM tool. I did like the original one more as well, and will bring this up to the digital tool creation team. 

      OPA810 and OPA863 can replace the ADA4807-1 with a focus on high power supplies. Also any of these devices at this filtered list would work depending on other specifications (the tool would have been useful here).

      The OPA810 has similar BW, noise specs, and is also RRIO but with lower bias currents as a FET-input amplifier. And, the OPA863 is similar AC wise, RRIO, noise, and lower quiescent current than the ADA4807-1. 

    Thank you,


  • Thanks Sima, that OPA863 looks about right, it does not appear to have a TINA reference design so that path is a dead end for me, 

    Oh well, off to other things, 

    The parametric match tool was intended to always come back with a range of options weighting the different match parameters - based on the old NSM Selguide parametric database which is one of the more accurate out there. The BOM tool kind of adds package and pinout matching info, which is also useful once you have IC level match.
