Features

─ Miniature construction ─ Low-Noise Output ─ 4.5 V to 6 V Operation ─ Magnetically Optimized Package ─ Linear output for circuit design flexibility ─ Temperature range of -40 °C to 150 °C 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA)

Description

SS4825 Linear Hall-effect sensor is small, ver- satile linear Hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The linear sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The integrated circuitry features low noise out- put, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide increased temperature stability and ac- curacy. The linear Hall sensor has an operating temperature range of -40 °C to 150 °C appropri- ate for commercial, consumer and industrial environments. Typical Applications ─ Motor control ─ Magnetic code reading ─ Ferrous metal detector ─ Current sensing ─ Position sensing Functional Block Diagram
