Claim:
1. A method for increasing a reliability of transducers having a first IC and a second IC, wherein the first and second IC have monolithically integrated circuit components each with one sensor and a signal contact designed for bidirectional data transmission, and a reference contact , and a supply voltage contact, the reference contact on the first and second IC being connected to or disconnected from the signal contact via a controllable switch, the method comprising: generating a signal as a function of a physical quantity sensed by the relevant sensor that is applied in each case to the signal contact, the first and second IC being integrated into a common IC package; connecting the supply voltage contact of the first IC to a first package contact, the first package contact being connected to a first terminal of a control unit; connecting the supply voltage contact of the second IC to a second package contact, the second package contact being connected to a second terminal of the control unit; connecting the reference contact of the first IC to a third package contact and to the reference contact of the second IC, the signal contact of the first IC is connected to the signal contact of the second IC and to a fourth package contact; transmitting the two signals through the fourth package contact to the control unit; and analyzing the two signals in the control unit.
