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. 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. 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 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 Honeywell APS00A instrumentation amplifier available for additional signal processing
