The A1304ELHLX-T is a Hall effect sensor manufactured by Allegro that comes in an SOT-23W package. It is a monolithic bipolar integrated circuit, designed to provide efficient and trouble-free operation in sensing magnetic fields to the degree of accuracy required for a wide range of applications. It features low power consumption, a wide operating temperature range (+85ºC to -40ºC) and a high temperature tolerant dielectric. The A1304ELHLX-T provides low-offset sensor output amplifiers for proportional Hall-effect sensing, as well as bidirectional, quadrature, magnetic encoder output signals. The A1304ELHLX-T is suitable for both home and industrial use, and can be used to detect the presence of magnets in electric motors, compressors, generators, and other magnetic systems.
