AS5040
10Bit 360° Programmable Magnetic Rotary Encoder
Data Sheet
1 General Description
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.
