Product Description
Allegro Microsystems A1326LLHLT-T is a surface mount linear Hall effect sensor designed for accurate magnetic field detection with a supply voltage between 4.5 V and 5.5 V. Packaged in a 3-pin SOT-23 format, this sensor integrates a Hall element, amplifier, and temperature compensation circuits, delivering precise, low-noise analogue output voltage proportional to the magnetic flux density.
Featuring BiCMOS chopper stabilization technology, the device minimizes offset and noise, ensuring high signal integrity. Its quiescent output voltage is temperature stable at half the supply voltage, with sensitivity fixed at 2.5 mV/Gauss. The supply current is a low 9 mA, with a rapid response time of 32 microseconds suitable for motion detection and dynamic sensing applications in industrial and automotive systems.
The sensor supports a broad temperature range from -40°C to 150°C, making it resilient in harsh environments. Lead-free construction promotes compliance with industry environmental standards. The compact surface mount SOT-23 package allows for efficient PCB space utilization and ease of manufacturing. This Hall effect sensor is ideal for magnetic field sensing in instrumentation, industrial automation, consumer electronics, and motion sensing applications.
