Introduction

A1389LLHLT-RP9-T is a type of magnetic sensor. It is a low power low drift magnetic sensor which provides full-scale current output that can be scaled, amplified, and rectified accurately. It is suitable for a wide range of applications such as current, voltage, and position sensing, magnetic compasses, and digital magnetometers. It is well known as a Magnetic Linear sensor due to its higher sensitivity and tighter range of linearity. It is also suitable for compass ICs, such as for inertial navigation, mapping, and positioning. This document provides a brief overview of the working principle and applications of the A1389LLHLT-RP9-T.

Working Principle

A1389LLHLT-RP9-T utilizes an integrator stage and a voltage divider to convert the sensed magnetic field into an electrical current output. The integrator stage consists of a capacitor and an op-amp. The voltage divider consists of two resistors. The capacitors are used to charge to the voltage at the output of the op-amp and the voltage divider is used to convert the current output to a voltage. When a magnetic field is applied, it induces a voltage in the closed loop formed by the capacitor, the resistor, and the current source. This induced voltage is proportional to the strength and direction of the magnetic field, and this voltage is the output of the A1389LLHLT-RP9-T.

Applications

As the A1389LLHLT-RP9-T provides a full-scale current output, it can be used in many applications. One application is for current, voltage, and position sensing. It is capable of measuring the direction and magnitude of a magnetic field, and this information can be used to determine the orientation and position of an object in three-dimensional space. It can also be used for digital magnetometers, which are used to measure the strength of a magnetic field. It is also suitable for compass ICs, such as for inertial navigation, mapping, and positioning. Finally, it is suitable for applications that require accurate measurements of extremely low magnetic fields, such as in medical imaging.
