A method and apparatus for minimizing errors in a sensor device due to signal amplitude variation are disclosed herein. A signal output from the sensor device is amplified and, thereafter, AC-coupled to a comparator such that the amplification and AC-coupling of the signal minimize offset shift-related errors associated with the sensor device. The signal can be coupled to eliminate offset shifts due to component mismatches, calibration, aging and/or temperature associated with the sensor device. An AC-coupled sensor signal conditioning circuit is utilized to amplify the signal through an amplifier and then AC-couple the signal to a comparator.
