INA128: lost precision under 10Krad gamma rays

Part Number: INA128

Hi Team,

Application scenario is for flow transmitter using INA128. INA128 lost precision under about 10Krad gamma rays. Does we have any special device can bare such radiation situation test and keep the precision? Thanks a lot.

Best Regards,

Tess Chen

  • Hi Tess,

    INA128 is not tested and certified as radiation hardened, so I am not surprised of your findings when the part is exposed to 10Krad gamma rays.

    What is your design application? Have you consider to shield the design or part with Pb or Al faraday shield. 

    You may try our INA818 IA part, but again this is not radiation hardened design or package against gamma ray and high energy wavelength.  The IA design has to do some Pb shielding to block the energy entering the EUT. 

    If you have additional questions, please let us know. 

    Best,
