Angle Sensors Cover 0° To 360°

Allegro MicroSystems’ A1330 0° to 360° angle sensor ICs provide contactless high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. They employ a system-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing, and either an analog or digital PWM output signal. The A1330 series is offered in both single and dual die versions for systems that require redundant sensors. They also include on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters.

 

Both devices are suitable for automotive applications requiring 0° to 360° angle measurements, such as motor position measurements for pumps and other actuators, that require low latency and high resolution. The A1330 also includes on-chip scaling to support “short stroke” applications with as little as 11.25° of motion, like valve position, pedal position, and fuel tank level sensing.
