APS00B

The APS00B is a high resolution angular position Sensor IC, it is a miniature surface mount device for angular or rotary displacement designed for magnetic saturating field sensing. The IC creates an analogue output voltage that varies with the direction of the magnetic flux passing over the sensor 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. This sensor IC uses Honeywell's Anisotropic Magnetoresistive (AMR) technology that provides advantages over Hall-effect-based magnetic sensors.

• Wide, angular range allows measurements ±90° and ±180°
• Resolution capability of less than 0.05° helps improve overall system accuracy
• Absolute sensing, no indexing is required, exact target position is known, simplifying system design
• Dual 4-element Wheatstone bridges provide a passive element
• Low-noise design
• Helps to improve system performance
• Typical 0 to 5MHz frequency response with 190G minimum magnetic field applied
• Saturated mode
• Typically requires only 5V at 4mA to operate (20mW), promoting energy efficiency
• Measure only field direction, virtually unaffected by shock, vibration/magnetic-source gap variation
• Provides stable and reliable output
• Dual bridges with outputs 45° out of phase make it possible to use outputs as speed/direction signal
