Precision Hall-effect angle sensor ICs

Allegro MicroSystems new family of contactless Hall magnetic sensors—the A1332 and A1334 high-resolution 360° angle sensor ICs—are based on magnetic circular vertical Hall technology. The A1332 and A1334 devices, with their system-on-chip architectures, provide fast output refresh rates and low signal path latency to support a variety of demanding automotive and industrial applications. Both devices are suitable for automotive applications such as electronic power steering, transmission, motor position, throttle/pedal position, and other systems that require accurate measurement of angles. The A1332 includes segmented and Fourier linearization functions for supporting challenging off-axis/side-shaft magnetic sensing configurations that are commonly found in electronic power steering and transmission applications. The A1334 is designed specifically for on-axis/end-of-shaft applications that require ultra-fast output refresh rates and low signal path latency.
