Allegro Microsystems 1 Axis Through Hole Hall Effect Sensor Linear BiCMOS Technology 4.5V-5.5V SIP Package 3-Pin A1325LUA-T

Allegro Microsystems A1325LUA-T is a high performance 1 axis linear Hall Effect sensor designed for precise detection of magnetic fields. It uses BiCMOS technology and operates within a supply voltage range of 4.5 V to 5.5 V. The sensor is housed in a compact through-hole SIP 3-pin package measuring 4.09 mm x 1.52 mm x 3.02 mm, facilitating ease of use in printed circuit board designs.

This sensor provides an analogue output voltage directly proportional to the applied magnetic flux, making it ideal for motion sensing and position detection. It integrates a Hall element with advanced temperature compensation circuitry ensuring stable output across a wide operating temperature range from -40°C to 150°C. The device also incorporates a small-signal high-gain amplifier, a clamped low-impedance output stage, and a proprietary dynamic offset cancellation technique to minimize noise and improve accuracy.

Typical applications include industrial automation, motor control, consumer electronics, and automotive systems where reliable magnetic field sensing is critical. The fast response time of 32 microseconds allows for quick signal processing, and the low 9 mA supply current makes it suitable for battery-powered or energy-efficient devices.

The package is RoHS compliant and lead-free, aligning with modern environmental regulations. This sensor combines robust performance, compact size, and wide operating conditions for versatile use in electronic sensor solutions.
