综述
The AS5270 is a dual-die, high-resolution angular position sensor for precise absolute angle measurement. The AS5270 is available with an analog output interface (AS5270A) or a digital output interface (AS5270B). The latter can be programmed as a PWM or a SENT-compliant output interface.
Based on a Hall sensor technology, this device measures the orthogonal component of the flux density (Bz) over a full turn rotation and compensates 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 the best resolution for the application. To measure the angle, only a simple two-pole magnet rotating over the center of the package is required. 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 AS5270 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.
The AS5270A is a stacked dual-chip for high-reliability redundant operation. In this device, two chips are aligned and encapsulated in the same package. Separate pins are provided for each chip, so no electrical fault in the device can affect both chips.
With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.
