Product Specification
| Description | SIP-4 Linear, Compass (ICs) RoHS | Mfr. Part # | A1468LK-W-T |
| Package | SIP-4 | Model Number | A1468LK-W-T |
The A1468 is an optimized Hall-effect sensing IC designed for digital ring-magnet sensing and ferromagnetic target sensing in three-wire applications. It features dual Hall-effect elements with integrated signal processing for switching based on differential magnetic signals. The device offers user-friendly solutions with features like running-mode calibration for continuous optimization, automatic gain control (AGC) for air-gap independent switch points, and automatic offset adjustment (AOA) for signal processing optimization, ensuring true zero-speed operation. Its compact package is suitable for various target shapes and sizes, making it ideal for speed, position, and timing applications such as in speedometers.
