A1688 Overview
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. The A1688 is offered in the UB package, which integrates the IC and a high temperature ceramic capacitor in a single overmolded SIP package.
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 reliability
- On-chip voltage regulator with wide operating voltage range and stability in the presence of a variety of complex load impedances
