The A1332 is a 360° contactless high resolution programmable magnetic angle position sensor IC. It is designed for digital systems using an I²C interface.
This system-on-chip (SoC) architecture includes a front end based on Circular Vertical Hall (CVH) technology, programmable microprocessor based signal processing, and digital I²C interface. Besides providing full-turn angular measurement, the A1332 also provides scaling for angle measurement applications less than 360°. It includes on-chip EEPROM technology for flexible programming of calibration parameters.
Digital signal processing functions, including temperature compensation and gain/offset trim, as well as advanced output linearization algorithms, provide an extremely accurate and linear output for both end of shaft applications, as well as off‑axis applications.
The A1332 is ideal for automotive applications requiring high speed 360° angle measurements, such as: electronic power steering (EPS), transmission, torsion bar, and other systems that require accurate measurement of angles. The A1332 linearization schemes were designed with challenging off-axis applications in mind.
The device is offered in a 14-pin TSSOP (LE) package, which has a single die. The package is lead (Pb) free, with 100% matte tin leadframe plating.
