DESCRIPTION
The integrated circuit incorporates dual Hall effect elements with a 2.2 mm spacing and signal processing that switches in response to differential magnetic signals created by ringmagnet poles. The circuitry contains a sophisticated digital circuit to reduce system offsets, to calibrate the gain for airgap–independent switchpoints, and to achieve true zero-speed operation. Signal optimization occurs at power-on through the combination of offset and gain adjust, and is maintained throughout the operating time with the use of a running-mode calibration.
