A1698

Two-Wire, True Zero-Speed, High Accuracy

Sensor IC with Speed and Direction Output

FEATURES AND BENEFITS

• 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

switchpoints

• 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

DESCRIPTION

The A1698 is a Hall-effect-based integrated circuit (IC) that

providesauser-friendlysolutionfortwo-wirespeedsensingof

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.

TheintegratedcircuitincorporatesHall-effectcircuitsandsignal

processing that switches in response to differential magnetic

signals created by magnetic encoders, or, when properly back-

biasedwithamagnet,fromferromagnetictargets.Thecircuitry

contains a sophisticated digital circuit that reduces magnet

and system offsets, calibrates the gain for air gap independent

switchpoints, and provides true zero-speed operation.

Package: 2-pin SIP (suffix UB)

circuitry and is ideally suited for obtaining speed and direction

informationinwheelspeedapplications.The2-pinSIP package

is lead (Pb) free, with tin leadframe plating.
