MA734

8-Bit to 12.5-Bit, 3μs Low-Latency Contactless Angle Sensor

Datasheet

Description

The MA734 is a MagAlpha digital angle sensor that detects the absolute angular position of a permanent magnet (typically a diametrically magnetized cylinder on a rotating shaft). Fast data acquisition and processing provide accurate angle measurements, from static angle measurements to high-speed rotation. The digital filtering is adjustable to optimize control loop performance when used in servo motor applications.

This sensor supports a wide range of magnetic field strengths and spatial configurations. Both end-of-shaft and side-shaft (off-axis mounting) configurations are supported. The MA734 detects the strength of the magnetic field, and includes configurable thresholds that can be used for push-button human-machine interface (HMI) applications, or for diagnostic purposes. On-chip, non-volatile memory (NVM) provides storage for configuration parameters, such as the reference zero-angle and magnetic field detection thresholds. It is also possible to configure the MA734 with volatile registers without accessing the NVM.

The MA734 is available in a QFN-16 (3mmx3mm) package.
