MagAlpha MA730 14-Bit, Digital, Contactless Angle Sensor with ABZ Incremental & PWM Outputs DESCRIPTION FEATURES The MA730 detects the absolute angular 14-Bit Resolution Absolute Angle Encoder position of a permanent magnet, typically a Contactless Sensing for Long Life diametrically magnetized cylinder on a rotating SPI Serial Interface for Digital Angle shaft. Fast data acquisition and processing Readout and Chip Configuration provide accurate angle measurements at Incremental 12-Bit ABZ Quadrature speeds from 0 to 60,000 rpm. Encoder Interface with Programmable Pulses Per Turn from 1 - 1024 The MA730 supports a wide range of magnetic PWM Output 14-Bit field strengths and spatial configurations. Both Programmable Magnetic Field Strength end-of-shaft and off-axis (side-shaft mounting) Detection for Diagnostic Checks configurations are supported. 3.3V, 12mA Supply The MA730 features magnetic field strength -40C to +125C Operating Temperature detection with programmable thresholds to Available in a QFN-16 (3mmx3mm) allow sensing of the magnet position relative to Package the sensor for creation of functions, such as the sensing of axial movements or for diagnostics. APPLICATIONS On-chip non-volatile memory provides storage General Purpose Angle Measurements for configuration parameters, including the High-Resolution Angle Encoders reference zero angle position, ABZ encoder Automotive Angle settings, and magnetic field detection Robotics thresholds.
