ams OSRAM AS5070 On-Axis Magnetic Angular Position Sensors are high-resolution, Hall-based rotary magnetic position sensors that utilize CMOS technology and provide precise absolute angle measurements. The AS5070 is available with an analog output interface (AS5070A) or a digital output interface (AS5070B). The AS5070B can be programmed as a PWM or a SENT-compliant output interface. These sensors measure the orthogonal component of the flux density (Bz) over a full turn rotation and compensate for external stray magnetic fields with a robust architecture based on a 14-bit sensor array and analog front-end (AFE). A sub-range can be programmed to achieve ideal application resolution.
A simple two-pole magnet rotating over the center of the package is required to measure the angle. The magnet may be placed above or below the device. The absolute angle measurement provides an instant indication of the magnet’s angular position. The AS5070 operates at a supply voltage of 5V, and the supply and output pins are protected against overvoltage up to +20V. In addition, the supply pins are protected against reverse polarity up to -20V.
