  • OPA180: cap across NC pins

    TI Thinks Resolved
    Part Number: OPA180 I would like to add OPA180 as a second source for LTC2057IMS8. I do not use the shut down functionality of the LTC2057 in my design, and I have a 0.1uF cap across pin 1 and 8. Pin 1 and 8 on the OPA180 are NC. Is it ok to leave this…

  • OPA180: Output inconsistent across multiple board

    Part Number: OPA180 Hello TI, I am using OPA180IDBVR in one of our design which is used as a differential mode to single ended amplifier with gain of 10. The issue is on physical measurement we are getting different values for the same input across different…
