INA110: Drop-in higher-temperature replacement for INA110KU

Part Number: INA110

Does anyone know a good drop-in high-temperature replacement for the INA110KU amp? I suddenly need to put my board in a 80C environment, and the INA110KU only goes to 70C. The INA110AG, -SG, and -BG are rated to 85C but I can't find them at Digikey or Mouser, and those might not be surface mount even if I could. Any suggestions?

  • Hi Joel,

    Thank you for your post. The INA110 is unique in that the gain resistors are internal to the device. We don't have another/newer INA with this feature that can withstand higher temperature ratings. Can you accept an INA with external adjustable gain?

  • Thanks, Tamara. I was hoping to just pop the INA110 off the board and pop in a new one without changing the rest of the circuit board.

    Is there a replacement that mostly uses the same pinout? Maybe I can jumper some resistors into the PCB somehow...

    Thanks

  • Hi Joel,

    I'm sorry, we don't have anything similar to that device. It is a unique one in our portfolio. All our newer INAs follow the standard package / pin out.
