AS5040

General Description AS5040 10-Bit 360º Programmable Magnetic Rotary Encoder The AS5040 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing 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 magnet’s angular position with a resolution of 0.35° = 1024 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. Furthermore, a user-programmable incremental output is available, making the chip suitable for replacement of various optical encoders. An internal voltage regulator allows the AS5040 to operate at either 3.3V or 5V supplies. Ordering Information and Content Guide appear at end of datasheet.
