APS00B Datasheet, PDF (1/6 Pages) Honeywell Solid State Electronics Center – High Resolution Magnetic Angular Position Sensor IC

APS00B
DESCRIPTION
Honeywell’s APS00B High Resolution Magnetic Angular
Position Sensor IC (Integrated Circuit) is a miniature surface
mount device for angular or rotary displacement designed for
magnetic saturating field sensing.
The APS00B creates an analog output voltage that varies with
the direction of the magnetic flux passing over the IC surface.
It contains dual saturated-mode Wheatstone bridges that
generate quadrature (sine and cosine) signals to provide an
extended range of angular measurements up to 180°.
This product is a cost-effective and space-efficient solution for
high volume OEM designs. Potential applications include
position sensing, rotary speed and angle detection, and non-
contact precision location measurement systems.
FEATURES AND BENEFITS
Wide angular range allows measurements of ±90° without
additional components make this device suitable for a variety
of angular sensing applications; ±180° measurement is
possible with external components
Resolution capability of less than 0.05° helps improve overall
system accuracy
Absolute sensing means no indexing is required and the
exact target position is known, simplifying the system design
Dual 4-element Wheatstone bridges provide a passive
element, low-noise design, helping improve system
performance
Small, SOIC-8 surface mount package saves room on the
PC board when compared to larger IC packages and
components
RoHS-compliant materials meet Directive 2002/95/EC
APS00B sensor ICs use Honeywell’s Anisotropic
Magnetoresistive (AMR) technology that provides advantages
over Hall-effect based magnetic sensors. They are able to
resolve better than a tenth of a degree or a tenth of a
millimeter, withstand large variations in magnet-to-sensor
gaps, and exhibit insensitivity to shocks and vibrations.
Honeywell’s Magnetic Sensors are among the most precision
and reliable position sensors in the industry.
These surface mount devices are mounted directly on the
electrical traces on a PC (printed circuit) board. They are
attached by an automatic solder reflow operation which
requires no hole, so it may help reduce the cost of the PC
board.
Tape and reel configuration allows use with automated pick-
and-place equipment, potentially reducing assembly costs.
(178 mm [7 in]) and 330 mm [13 in] reels available)
Typical 0 MHz to 5 MHz frequency response with 190 G
minimum magnetic field applied, makes this saturated mode
sensor IC potentially suitable for high speed applications
Typically requires only 5 V at 4 mA to operate (20 mW),
promoting energy efficiency
The devices measure only field direction and are virtually
unaffected by shock, vibration and magnetic-source gap
variations, providing a stable, reliable output
Dual bridges with outputs 45° out of phase make it possible
to use outputs as speed and direction signals
