AS5045-ASST Integrated Circuit Chip 12-Bit Programmable Magnetic Rotary Position Sensor
The AS5045 is a contactless magnetic position sensor 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 0.0879° = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.
An internal voltage regulator allows the AS5045 to operate at either 3.3 V or 5 V supplies. Ordering Information and Content Guide appear at end of datasheet.
