AS5046 Programmable 360° Magnetic Angle Encoder
AS5046
PROGRAMMABLE 12-bit 360° MAGNETIC ANGLE ENCODER
WITH ABSOLUTE 2-WIRE SERIAL AND ANALOG INTERFACES
PRELIMINARY FACT SHEET
DATA SHEET
General Description
The AS5046 is a contactless magnetic angle encoder for
accurate measurement up to 360°.
It is a system-on-chip, combining integrated Hall elements,
analog front end and digital signal processing in a single
www.DataSheet4U.com device.
The AS5046 provides a digital serial 12-bit as well as a
programmable 10-bit ratiometric analog output that is
directly proportional to the angle of a magnet, rotating over
the chip.
In addition, the serial interface enables a user configurable
arrangement of the Hall array and allows access to each
individual Sensor of the Hall Array.
The AS5046 also provides high resolution information of
the magnetic field strength, respectively the vertical
distance of the magnet, thus adding excellent state-of-
health information of the overall system.
An internal voltage regulator allows operation of the
AS5046 from 3.3V or 5.0V supplies.
Key Features
• 360° contactless high resolution angular position encoding
• User programmable zero position
• 12-bit 2-wire serial interface
• Versatile analog output
programmable angular range up to 360°
programmable ratiometric output voltage range
• High resolution magnet distance indication
256 steps within recommended range (~0.5 to 1.8mm)
256 steps over extended range (~0 to 5mm)
• Mode input for optimizing noise vs. speed
• Alignment mode for magnet placement guidance
• Wide temperature range: - 40°C to + 125°C
• Small package: SSOP 16 (5.3mm x 6.2mm)
Applications
The AS5046 is ideal for applications that require high
resolution, a minimum of wires between controller and
sensor and where the vertical distance of the magnet is of
importance:
• Remote sensors
• Rotate-and-push manual input devices
• Joysticks
• Applications with extended safety requirements
regarding magnet distance
