MagAlpha MA330 14-Bit, Digital, Contactless Angle Sensor with ABZ & UVW Incremental Outputs DESCRIPTION FEATURES The MA330 detects the absolute angular 9-Bit to 14-Bit Resolution Absolute Angle position of a permanent magnet, typically a Encoder diametrically magnetized cylinder on a rotating Contactless Sensing for Long Life shaft. Fast data acquisition and processing SPI Serial Interface for Digital Angle provide accurate angle measurement at speeds Readout and Chip Configuration from 0rpm to 60,000rpm. The digital filtering is Incremental 12-Bit ABZ Quadrature adjustable to optimize control loop performance Encoder Interface with Programmable when used in servo applications. Pulses Per Turn from 1 to 1024 UVW Interface with 1-Pole to 8-Pole Pair The MA330 supports a wide range of magnetic Emulation 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 MA330 features magnetic field strength -40C to +125C Operating Temperature detection with programmable thresholds to allow Available in a QFN-16 (3mmx3mm) sensing of the magnet position relative to the Package sensor for creation of functions such as sensing axial movements or for diagnostics. APPLICATIONS On-chip, non-volatile memory provides storage Brushless DC Motor Servo Drives for configuration parameters, including the Motor Commutation reference zero angle position, ABZ encoder Motor Speed and Position Control settings, UVW pole pair emulation settings, and Robotics magnetic field detection thresholds.
