MagAlpha MA732 14-Bit, Digital, Contactless Angle Sensor with ABZ Incremental & PWM Outputs DESCRIPTION FEATURES The MA732 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 measurements at Readout and Chip Configuration speeds from 0rpm to 60,000rpm. The digital Incremental 12-Bit ABZ Quadrature filtering is adjustable to optimize control loop Encoder Interface with Programmable performance when used in servo applications. Pulses per Turn from 1 to 1024 14-Bit PWM Output The MA732 supports a wide range of magnetic Programmable Magnetic Field Strength field strengths and spatial configurations. Both Detection for Diagnostic Checks end-of-shaft and off-axis (side-shaft mounting) 3.3V, 12mA Supply configurations are supported. -40C to +125C Operating Temperature The MA732 features magnetic field strength Available in a QFN-16 (3mmx3mm) detection with programmable thresholds to allow Package sensing of the magnet position relative to the sensor for creation of functions, such as the APPLICATIONS sensing of axial movements or for diagnostics. General Purpose Angle Measurements On-chip, non-volatile memory provides storage High-Resolution Angle Encoders for configuration parameters, including the Automotive Angle reference zero angle position, ABZ encoder Robotics settings, and magnetic field detection All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
