The A1334 is a 360° contactless, high-resolution programmableMagnetic angular position sensorIC。 It is suitable for digital systems that use the I²C interface.
This system-on-chip (SoC) architecture includes a front end based on Circular Vertical Hall (CVH) technology, a programmable microprocessor based on signal processing, and a digital I²C interface. In addition to rotating angle measurements, the A1332 can be scaled to meet angle measurement applications less than 360°. It includes on-chip EEPROM technology for flexible programming of calibration parameters.
Digital signal processing features, including temperature compensation and gain/offset correction, and advanced output linearization algorithms provide an extremely accurate linear output for both dual-axis and off-axis applications.
The A1332 is ideal for automotive applications that require high-speed 360° angle measurement, such as electronic power steering (EPS), transmissions, torsion bars, and other systems that require accurate angle measurement. The A1332 linearization scheme meets the needs of challenging off-axis applications.
The device is available in a 14-pin TSSOP (LE) package with a die on the package. The package is lead (Pb) free with 100% matte tin leadframe plating.
