Abstract
The present disclosure relates to a sensor circuit having a first interface configured to receive a first sensor signal in response to a first measurement of a first physical quantity, a first analog-to-digital converter configured to sample the first sensor signal to generate a sampled first sensor signal, a second interface configured to receive a second sensor signal in response to a second measurement of the same first physical quantity, a third interface configured to receive at least one third sensor signal in response to at least one third measurement of at least one second physical quantity that is different from the first physical quantity, a multiplexer configured to multiplex the second and the at least one third sensor signal to a multiplexed sensor signal, and a second analog-to-digital converter coupled to the multiplexer and configured to sample the multiplexed sensor signal to generate a sampled multiplexed sensor signal.
