  • RE: THS4061: TI-PSpice does not show the real behaviour of THS4061 after input override

    Oh and there is a very conspicous exception to spec overdrive recovery, that is the OPA698 and OPA699 output limiting amplifiers - everything was designed internally to recover very fast from ovedrive into settable output limits.
