FEATURES AND BENEFITS

DESCRIPTION

temperature range

The A1667 is a true zero-speed ring magnet sensor integrated

circuit (IC) consisting of an optimized Hall IC available in

two package options that provides a user-friendly solution for

digital ring magnet sensing applications.

▪ꢀTrueꢀzero-speedꢀoperation

The sensor incorporates a dual element Hall IC that switches

in response to differential magnetic signals created by a

ring magnet. The IC contains a sophisticated compensating

circuit designed to eliminate the detrimental effects of magnet

and system offsets. Digital processing of the analog signal

provides zero-speed performance independent of air gap and

also dynamic adaptation of device performance to the typical

operatingconditionsfoundinautomotiveapplications(reduced

vibration sensitivity). High-resolution peak detecting DACs

are used to set the adaptive switching thresholds of the device.

Hysteresis in the thresholds reduces the negative effects of any

anomalies in the magnetic signal associated with the targets

used in many automotive applications.
