General Description

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 capacitor in a single overmolded SIP package.

The integrated capacitor provides enhanced EMC performance.

Overview

A1698 Two-Wire, True Zero-Speed, High Accuracy Sensor IC with Speed and Direction.

Key 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 digita.
