Claim 0:
1. A sensor system, comprising:
a microcontroller comprising:
a first analog signal interface, and
a first bidirectional digital signal interface; and

at least three sensor chips, each sensor chip of the at least three sensor chips being configured to measure a physical quantity and comprising:
a second analog signal interface, and
a second bidirectional digital signal interface;

wherein the microcontroller and each sensor chip of the at least three sensor chips are coupled to one another via the first analog signal interface and the second analog signal interface and via the first bidirectional digital signal interface and the second bidirectional digital signal interface,
wherein the microcontroller and each sensor chip of the at least three sensor chips are coupled to one another via the first analog signal interface and the second analog signal interface to enable analog measurement data to be transmitted from each sensor chip of the at least three sensor chips and received by the microcontroller via an analog communication path, and
wherein the microcontroller and each sensor chip of the at least three sensor chips are coupled to one another via the first bidirectional digital signal interface and the second bidirectional digital signal interface to enable digital secondary information to be transmitted between each sensor chip of the at least three sensor chips and the microcontroller via a digital communication path.
