Patent ID: 8170237

Claim:
A semiconductor die with an integrated electronic circuit, configured so as to be mounted in a housing with a capacitive transducer; the electronic circuit comprising: a first circuit configured to receive an input signal from the transducer at an input node and to provide an output signal at a pad of the semiconductor die; where the integrated electronic circuit comprises an active device with a control input, coupled to a pad of the semiconductor die, to operatively engage or disengage a second circuit interconnected with the first circuit so as to operate the integrated electronic circuit in a mode selected by the control input; wherein the second circuit is interconnected with the first circuit so as to be separate from the input node, wherein the input node is coupled to the output at least via a signal conditioning circuit; the signal conditioning circuit comprises a first unit with a first parameter and a second unit with a second parameter controllable by the second circuit and the active device; the parameters of the first and second units in combination operatively determine a property of the signal conditioning circuit; and wherein said first and second units are embodied on the semiconductor die.
