1. A device, comprising:
an analog main signal path configured to amplify and output an analog sensor signal of a sensor at a digitally-controllable output amplitude, and a digital control circuit coupled with the analog main signal path and configured to determine a digital control signal and to provide the digital control signal to the analog main signal path to reduce a gain error of the analog main signal path, wherein the analog main signal path is configured to set the digitally-controllable output amplitude depending on the digital control signal.
