Abstract
A device and a method evaluate signals from one or more Wheatstone bridges. The requirements of ISO 26262 are taken into account by mixing a test signal with the measurement signal before amplification and before analog-to-digital conversion. After amplification and analog-to-digital conversion, the measurement signal and the test signal are unmixed again. If the test signal does not meet the expectation, the amplifier and/or the analog-to-digital converter is determined to be faulty.
