programmable magnetic angle sensor ic with spi i2c sent outputs and on chip eeprom allegro a1335lletr-t
Product Overview
The A1335 is a 360 contactless high-resolution programmable magnetic angle position sensor IC designed for digital systems. It offers communication via I2C, SPI, or SENT interfaces and features a system-on-chip (SoC) architecture with Circular Vertical Hall (CVH) technology, programmable microprocessor-based signal processing, and on-chip EEPROM for flexible calibration parameter programming. The sensor provides full-turn angular measurement, scaling for angles less than 360, and includes digital signal processing for temperature compensation, gain/offset trim, and advanced linearization algorithms, ensuring accurate and linear output for both end-of-shaft and off-axis applications. It is ideal for automotive applications such as electronic power steering (EPS), transmission, and torsion bar systems requiring high-speed 360 angle measurements.
