Hi Team,

Is there TI solution to replace ADI AD8634HRZN? AD8634HRZN temperature is -40C to 175C, however OPA2210IDR only up to 125C.

Please suggest. Thanks.

    to User473,

    I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed).   There are 6 options with temperatures of 150C and above (see attached).  The best match is the OPA211-HT (210C max).  This is the single channel version of the OPA2211-HT.  If a single channel option is reasonable this device might work.  The OPA2333-HT does go to 210C, and it is also a dual, but this device has a 5V power supply.  I will let the systems team know that there is a need for a dual precision high temperature op amp, but currently I do not think there is a good dual channel match.

    Best regards, Art
