A1334 - Allegro MicroSystems

A1334 Micro Power Hall-Effect Angle Sensor

The A1334 is a 360° angle sensor IC that provides contactless high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and a digital (SPI) output. The A1334 is ideal for automotive applications requiring high-spe.
