AS5043 10-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
Adapter PCB Operation Manual
2 General Description
The AS5043 is a system-on-chip, combining
integrated Hall elements, analog front end and
digital signal processing in a single device. It
provides incremental output signals and the
absolute angular position of a magnet that is placed
either above or below the device.
The AS5043 can be configured to specific customer
requirements by programming the integrated OTP
(one time programmable) register. An internal
voltage regulator allows the AS5043 to operate at
either 3.3 V or 5 V supplies.
