A1335

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或发送界面。

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和发送。除了提供全转角测量外，A1335还提供小于360°的角度测量应用的缩放。亚博尊贵会员它包括片上的EEPROM技术，能够支持多达100个读/写周期，以灵活地编程校准参数。

数字信号处理功能，包括温度补偿和增益/偏移装饰，以及先进的输出线性化算法，为轴端和轴外应用提供极其准确和线性的输出，以及轴外应用。亚博尊贵会员

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.
