Load current determining circuit arrangement for semiconductor switch, has deactivation circuit to temporarily deactivate offset compensation arrangement, which is coupled to input of amplifier, for period after level change of signals

摘要

The arrangement has an amplifier arrangement (10) with an operational amplifier (11) including an input and an output that are coupled to an input and an output of the arrangement (10), respectively. An offset compensation arrangement (20) is coupled to the input of the amplifier and provides an offset compensation signal. A deactivation circuit (30) temporarily deactivates the arrangement (20) for a period after a level change of input signals.
