INA333-HT: for Avionics use?

Part Number: INA333-HT
Other Parts Discussed in Thread: INA129-HT

Hello Guys,

Good day.

Just like to confirm: INA333-HT is Military qualified. Does it mean its okay for Avionics/Aircraft application?

Customer don't necessarily need Space grade products, and we do not have Space grade qualified Instrumentation Amplifier.

Thanks and regards,

Art

  • Hi Art,

    Just like to confirm: INA333-HT is Military qualified. Does it mean its okay for Avionics/Aircraft application?

    Yes, INA333-HT is applicable for Avionic/Aircraft application, which its operating temperature is rated between -55C and +150C. In addition, the input analog front end of INA333-HT are built in with RFI filter, which it will further help to to pass radiated and conducted susceptibility tests other EMI/EMC DO-160 test requirements. 

    If you have additional questions, please let me know.

  • Thanks Raymond!

    How about INA129-HT? I do not see RFI related information on its datasheet but it is Military qualified as well. Is it okay for Avionics too?

    Thanks and regards,

  • Hi Art,

    INA129-HT will be applicable for Avionics as well. 

    RFI input filter features are not required, but the wide operating temperature range is the minimum Avionics requirements. Depending on the use of the application and location used in an aircraft, a designer can always place filter and protection circuitry per design requirements, so its analog front end is able to withstand and meet an interface coupling and cable bundle requirements for a design that is in compliance with DO-160 test and certification requirements.

    If you have additional questions, please let me know. 

    Best,
