LOW OFFSET OP-AMP

Guru 13485 points
Other Parts Discussed in Thread: OPA735, LMV641, LMV841, OPA2188

looking for OPAMP,Vcc max=12v or more,Offset=less then 60uv,Rail 2 rail,Size=SC70

I found the OPA735 which meet these4 parameters but not in SC70 package.

 

  • Hi Eli,

    Unfortunately, I do not see any low offset devices in SC-70's, either.

    The closest matches would be the LMV641 or LMV841 in a SC-70 - but both are 500uV room max.

    Unfortunately, "precision" devices are tough to fit into small packages due to trimming structures and/or larger input devices. Choppers need room for the CMOS front-end switches and internal loop filters. So you do not see many high precision devices in tiny packages.

     It looks like the smallest packages available will be the SOT-23, with most in the MSOP-8 or LLP package (OPA2188/OPAx735/OPAx211).

    Sorry...you may have to "downgrade" to a SOT-23 or MSOP-8.

    Regards,
