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 3.3 V or 5 V supplies.
Ordering Information and Content Guide appear at end of
datasheet.
