    PSOC4 OPAMP Startup time

    user_464067425

      I noticed that it takes approximately 500ms after power on to get a valid output from the internal Opamp of the Psoc4 (configured as voltage follower)

      The further behavior after this (long) time is interesting too: there is a bit of overshooting and a spike in the output signal.

      My problem is that I need the output signal immediately after startup because there is some external circuit (comparators etc.) which rely on the signal.
      Is it possible to start the Opamps "immediately" after power on or is it necessary to use external Opamps?
