AS5048A/AS5048B
Magnetic Rotary Encoder
14-bit Angular Position Sensor
Datasheet
General Description
The AS5048 is an easy to use 360° angle position sensor with a 14-bit high resolution output. The maximum system
accuracy is 0.05° assuming linearization and averaging is done by the external microcontroller.
The IC measures the absolute position of the magnet’s rotation angle and consists of Hall sensors, analog digital
converter and digital signal processing. The zero position can be programmed via SPI or I²C command. Therefore no
programmer is needed anymore. This simplifies the assembly of the complete system because the zero position of
the magnet does not need to be mechanically aligned. This helps developers to shorten their developing time. The
sensor tolerates misalignment, air gap variations, temperature variations and as well external magnetic fields. This
robustness and wide temperature range (-40°C up to +150°C) of the AS5048 makes the IC ideal for rotation angle
sensing in harsh industrial and medical environments. Several AS5048www.DataSheet.co.kr ICs can be connected in daisy chain for serial
data read out. The absolute position information of the magnet is directly accessible over a PWM output and can be
read out over a standard SPI or a high speed I²C interface. Version AS5048A comes with SPI and PWM Interface.
Version AS5048B is configured with the I²C interface and has also a PWM output. An internal voltage regulator
allows the AS5048 to operate at either 3.3 V or 5 V supplies.

2 Electrical Characteristics
2.1 Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to the device. These are stress ratings only. Functional operation of
the device at these or any other conditions beyond those indicated under “Operating Conditions” is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
