MA734

8-Bit to 12.5-Bit, 3µs Low-Latency

Contactless Angle Sensor

DESCRIPTION

FEATURES

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

measurement to high-speed rotation. The digital

filtering is adjustable to optimize control loop

performance when used in servo motor

applications.



Programmable 8-Bit to 12.5-Bit Resolution

Absolute Angle Encoder



3µs of Latency at Constant Rotation Speed

SPI Serial Interface for Digital Angle

Readout and Chip Configuration

Programmable Magnetic Field Strength

Detection for Diagnostic Checks

NVM Read/Write Command Extends

Memory Life



3.3V, 11mA Supply Current

-40°C to +125°C Operating Temperature

0rpm to 60,000rpm Rotation

Interrupt Out when Angle Change Is

Detected

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.



Available in a QFN-16 (3mmx3mm)

Package

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. An 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 program the MA734 with volatile

registers without accessing the NVM.

APPLICATIONS



General-Purpose Angle Measurement

High-Resolution Angle Encoders

Automotive Position Sensing
