AS5046 12-BIT PROGRAMMABLE MAGNETIC ROTARY ENCODER
Adapter PCB Operation Manual
2 General Description
The AS5046 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 AS5046 can be configured to specific customer
requirements by programming the integrated OTP (one
time programmable) register. An internal voltage
regulator allows the AS5046 to operate at either 3.3 V or
5 V supplies.

Type
Magnet Field Magnitude RaNGe warning;
active low, indicates that the magnetic
field strength is outside of the
recommended limits.
Mode input. Select between low noise
(open, low) and high speed (high) mode.
