The A1335 is a 360° contactless high-resolution programmable magnetic angle position sensor IC. It is designed for digital systems and is capable of communicating via an I2C, SPI, or SENT interface.
This system-on-chip (SoC) architecture includes a front end based on Circular Vertical Hall (CVH) technology, programmable microprocessor-based signal processing, and features an interface capable of supporting I2C, SPI, and SENT. Besides providing full-turn angular measurement, the A1335 also provides scaling for angle measurement applications less than 360°. It includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, 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 A1335 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 A1335 linearization schemes were designed with challenging off-axis applications in mind.
The A1335 is available as a single die in a 14-pin TSSOP, or dual die in a 24-pin TSSOP. Both packages are lead (Pb) free with 100% matte-tin leadframe plating.
