The A1381LLHLT-T is a Hall-effect linear magnetic sensor IC that offers superior sensitivity and accuracy in linear and compass applications. The IC is designed with a low-offset, low-noise, and low-temperature coefficient Hall circuit for enhanced accuracy in applications requiring precise sensing. The IC is an easy-to-use, highly cost-effective solution offering high levels of performance and reliability.

The A1381LLHLT-T IC integrates and encapsulates a Hall sensor and a signal resolver on a monolithic CMOS integrated circuit. When a magnetic field is incident on the hall-effect element, a voltage signal proportional to the magnetic field’s strength and polarity is generated at the Hall-effect element. The signal resolver then converts this analog signal into a digital signal through an internal axial ADC. The chip is able to automatically detect and calibrate itself to any background magnetic field present, eliminating the need for manual calibration.

The A1381LLHLT-T IC is ideal for use in linear and compass applications. It\'s capable of operating accurately over a wide range of temperatures and requires minimal additional circuitry, ensuring it will not take up a large portion of space within compact systems. The chip\'s low operating voltage of 0.8V to 4.5V and low current draw makes it an ideal choice for applications requiring low power consumption. The chip also provides an analog voltage output option for applications requiring the signal to be read directly.

The A1381LLHLT-T IC is designed to detect subtle variations in the magnetic field produced by the Earth\'s magnetic field. This makes it perfect for use in compasses, for calculating the direction and distance traveled, for positioning in mobile devices, and in navigation systems. Additionally, the chip can be used to accurately measure and classify objects in the vicinity based on their magnetic properties, such as ferromagnetic and diamagnetic materials.

In linear applications, the A1381LLHLT-T IC can be used to detect the presence and intensity of a linear magnetic field. This makes it ideal for use in applications requiring high-precision and reliable sensing such as in sensors used to detect the presence of metallic objects and in proximity sensing. Additionally, the IC can be used to measure movement or position of linear objects, such as measuring the movement and position of motor vehicles or any linear structure.

The A1381LLHLT-T IC is designed for fast and accurate magnetic sensing. Its integrated signal resolver can provide high-resolution measurements in a wide temperature range while consuming low power. Additionally, its small package size and low operating voltage make it a perfect fit for many applications requiring precise magnetic sensing with efficient power consumption.
