Patent ID: 7256602

Claim:
A test apparatus for testing electrical circuits, including integrated circuits, in particular of dynamic A/D converters, the test apparatus comprising: at least one input contact configured for connection to an integrated circuit; an electrical short-circuit protective circuit provided for each input contact, the electrical short-circuit protective circuit comprising: an input configured for connection to a signal generator; an output configured for connection to the input contact configured for connection to the integrated circuit; where the input contact configured for connection to the integrated circuit can be decoupled from the region lying upstream of the input of the electrical short-circuit protective circuit by the electrical short-circuit protective circuit; the output of, in each case, one electrical short-circuit protective circuit is connected to the associated input contact configured for connection to the integrated circuit; a signal generator, which is configured to generate a test signal and which is connected to each input of the electrical short-circuit protective circuit or circuits via one connecting line in each case.
