AS5163 DB ams

AS5163 12-Bit Automotive Angle Position Sensor The AS5163 is a contactless magnetic angle position sensor for General Description accurate angular measurement over a full turn of 360. A sub range can be programmed to achieve the best resolution for the application. It is a system-on-chip, combining integrated Hall elements, analog front-end, digital signal processing and best in class automotive protection features in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC. The absolute angle measurement provides instant indication of the magnets angular position with a resolution of 0.022 = 16384 positions per revolution. According to this resolution the adjustment of the application specific mechanical positions are possible. The angular output data is available over a 12-bit PWM signal or 12-bit ratiometric analog output. The AS5163 operates at a supply voltage of 5V and the supply and output pins are protected against overvoltage up to +27V. In addition, the supply pins are protected against reverse polarity up to -18V. Ordering Information and Content Guide appear at end of datasheet.
