A1688 - High Accuracy Sensor

General Description

The A1688 is a Hall-effect-based integrated circuit (IC) that provides a user-friendly solution for true zero-speed digital ring magnet and gear tooth sensing in two-wire applications.

Key Features

  • Integrated capacitor reduces need for external EMI protection components.
  • Wide leads facilitate ease of assembly.
  • True zero-speed operation.
  • Automatic Gain Control (AGC) for air gap independent switch points.
  • Automatic Offset Adjustment (AOA) for signal processing optimization.
  • Large operating air gap range.
  • Internal current regulator for two-wire operation.
  • Undervoltage lockout.
  • Single chip sensing IC for high rel.
