AS5045

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.

General Description

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.
