MA700 Angular Sensor: Pinout, Features and Datasheet

Q: What is the essential property of the MA700?

The MA700 is a robust contactless angle encoder. The IC detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder attached to the rotor.

Q: How many programmable registers does the MA700 contain?

The MA700 incorporates 3 programmable registers. Each register has 8 bit of memory.

Q: What is the area range of sensitive volume of MA 700?

The sensitive volume of the MA 700 is confined in a region less than 100 µm wide and consists of multiple integrated Hall devices.

MA700 Overview

The MagAlpha MA 700 is a robust contactless angle encoder. The IC detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder attached to the rotor. The MagAlpha is an extremely fast acquisition and processing sensor, allowing accurate angle measurement at speeds from 0 to 120’000 RPM.

Since the measurement is spatially confined, the user has flexibility in terms of magnet shapes and configurations. This can help relaxing mechanical tolerances and, in case the end of shaft position is not available, the MagAlpha 700 can also operate away from the axis of rotation (“side-shaft” mounting).

This article provides you with a basic overview of the MA700 Angular Sensor, including its pin descriptions, features and specifications, etc., to help you quickly understand what MA700 is.

MA700 Power Supply Decoupling

For most applications, a single 100 nF bypass capacitor placed close to the supply pins sufficiently decouples the MA 700 from noise of the power supply. If better decoupling is required, a larger capacitor (10 µF) can be added in parallel with the 100 nF, and/or a resistor (10Ω) can be added between the supply line and the capacitor node.

In any case, make sure that the connection between the MA 700 ground and the power supply ground has a low impedance, in order to avoid noise transmitted from the ground.

VFLASH needs to be supplied only when flashing the memory. Otherwise the VFLASH pin can remain unconnected or grounded (see the below Figure).
