Data Sheet - Pin Configuration
AS5043
Programmable 360° Magnetic Angle Encoder
with Absolute SSI and Analog Outputs
Data Sheet
1 General Description
The AS5043 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 device.
The AS5043 provides a digital 10-bit as well as a
programmable analog output that is directly proportional
to the angle of a magnet, rotating over the chip.
The analog output can be configured in many ways,
including user programmable angular range, adjustable
output voltage range, voltage or current output, etc..
An internal voltage regulator allows operation of the
AS5043 from 3.3V or 5.0V supplies.
2 Benefits
Complete system-on-chip
Flexible system solution provides absolute output,
both digital and analog
Angle measurement with software programmable
range up to 360°
High reliability due to non-contact magnetic sensing
3 Key Features

encoding
User programmable zero position
Two 10-bit absolute outputs:
Serial digital interface and
Versatile analog output
programmable angular range up to 360°
programmable ratiometric output voltage range
Failure detection mode for magnet field strength
and loss of power supply
Serial read-out of multiple interconnected
AS5043 devices using daisy chain mode

Alignment mode for magnet placement guidance
Wide temperature range: - 40°C to + 125°C
Small package: SSOP 16 (5.3mm x 6.2mm)
4 Applications
The AS5043 is ideal for applications with an angular
travel range from a few degrees up to a full turn of
360°, such as
Ideal for applications in harsh environments
