General Description

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.

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.

Overview

A1667 True Zero-Speed High Accuracy Ring Magnet Sensor IC.

Key Features

  • Optimized robustness to magnetic offset variation.
  • Small signal lockout for immunity against vibration.
  • Tight duty cycle and timing accuracy over full operating temperature range.
  • True zero-speed operation.
  • Air gap independent switch points.
  • Large operating air gaps achieved through use of gain adjust and offset adjust circuitry.
  • Defined power-on state (POS).
  • Wide operating voltage range.
  • Digital output representing target profile.
  • Single chip s.
