A1698 - Allegro Micro Systems

A1698 High Accuracy Sensor

The A1698 is a Hall-effect-based integrated circuit (IC) that provides a user-friendly solution for two-wire speed sensing of ring magnets or ferrous targets (when back-biased by the user) down to zero-speed in applications where speed and direction is required. The A1698 is offered in the UB package, which integrates the IC and a high temperature ceramic ca.

Features

• Integrated capacitor for EMC suppression in a single overmolded miniature package
• Wide leads facilitate ease of assembly
• True zero-speed operation
• Pulse-width output protocol
• Automatic Gain Control (AGC) for air gap independent switch points
• Automatic Offset Adjustment (AOA) for signal processing optimization, providing large operating air gap range
• Single chip sensing IC for high reliability
• Fully synchronous digital logic with Scan and IDDQ testing Package: 2-pin SIP (suffix UB) DESCRIPTION The A1698 is a Hall-effect-based integrated circuit (IC) that provides a user-friendl.
