A1688 High Accuracy Sensor

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 singl.

A1688 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
