Product Description
Product Overview
The A33230 is an integrated circuit (IC) 3D Hall-effect sensor designed for precise position sensing of magnetic targets. It features orthogonal vertical and planar Hall-effect elements, providing inherent 90 phase separation independent of magnet pole spacing and air gap. The IC offers independent sine and cosine outputs and comes pre-programmed for XY, XZ, or YZ axis combinations. User-defined linearization and error compensation may be necessary. The A33230 is supplied in a compact, RoHS-compliant 5-pin SOT23-W package with a lead-free, 100% matte-tin leadframe plating.
