Embodiments of the invention described herein provide a magnetic sensorinterfacecapable of adjusting signal conditioning dynamically using a speed signal of atarget suchthat the true positive and negative peaks of the input signal are maintainedfor the giventarget across its entire speed range (0-Max rpm), therefore increasing thesignal to noiseratio at low speeds and avoiding clipping or distortion at high speeds. In oneaspect, amethod comprises receiving an alternating differential voltage signal from asensor. Thedifferential voltage signal has an amplitude that changes relative to a changein speed of atarget. The alternating differential voltage signal is converted to anattenuatedsingle--ended voltage signal that can be dynamically scaled. The attenuatedsingle-ended voltagesignal can be scaled by multiplying the attenuated single-ended voltage signalby ascaling factor. The scaling factor is selected relative to the speed signaland is selectedrelative to a signal-to-noise ratio of the scaled attenuated single-endedvoltage signal.
