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.
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.
