Hi,

Do you have a -55C operating part number for OPA191?

Thanks

Shihab.

    Hello Shihab,

    I did a search of the TI products and did not find a version of the OPA191 that is specified with a -55 C low end operating temperature; -40 C is its lowest temperature. Would the OPA188 be a consideration? It is specified with a -55 C operating temperature and has similar electrical specifications.

    Thanks Thomas for the reply,

    I was trying to get a replacement for TLE2061MD. OPA191 has lesser quiescent current spec compared to TEL2061. Also it can drive high loads.

    Can you provide an op-amp which has following spec.

    GBWP: ~2.5MHz

    Power supply : +/- 15V

    Temp range: -55 to +125C

    Quiescent current: <390uA

    Output drive: 20mA (over the operating temp). output swing should be capable of with in 1.5V of the power supply rails.

    Reduction of Aol with respect to loading should be better than TLE2061.

    Thanks,

    Shihab.
