Product Description

Chip Overview

The KTH5502 is a high‑precision absolute angle sensor chip based on vertical Hall technology, supporting full‑range (0‑360°) angle measurement. Internally integrated with X‑ and Y‑axis vertical Hall elements as well as a Z‑axis planar Hall element, the chip can simultaneously sense magnetic‑field variations along the X, Y and Z axes.

Benefiting from the excellent orthogonality matching performance, low‑offset design and high‑performance signal chain of vertical Hall technology, the KTH5502 converts magnetic‑field signals into digital signals via on‑chip high‑precision amplifier circuits and a 16‑bit ADC. Combined with dedicated algorithm processing, it delivers high‑resolution absolute‑angle output in the XY plane.
