Product Overview
The A1335 is a 360 contactless high-resolution programmable magnetic angle position sensor IC designed for digital systems. It features Circular Vertical Hall (CVH) technology and offers digital output via I2C, SPI, or SENT interfaces. The system-on-chip (SoC) architecture includes programmable signal processing, on-chip EEPROM for flexible calibration, and advanced linearization algorithms for accurate angle measurements in both end-of-shaft and off-axis applications. Ideal for automotive systems like electronic power steering (EPS), transmission, and torsion bar, it is available in single or dual die TSSOP packages.
