Hallwee HAL4901UA

HAL490x, a linear Hall-effect sensor, is composed of Hall sensor, linear amplifier and Totem-Pole output stage. It features low noise output, which makes it unnecessary to use external filtering. It also can provide increased temperature stability and accuracy. The linear Hall sensor has a wide operating temperature range of -40℃ to +125℃ appropriate for commercial, consumer, and industrial environments. The high sensitivity of Hall-effect sensor accurately tracks extremely weak changes in magnetic flux density. The linear sourcing output voltage is set by the supply voltage and in proportion of vary of the magnetic flux density. Typical operation current is 1.8 mA and operating voltage range is 2.8 volts to 6.0 volts. Trim version is available for an ultra low offset products. The two package styles available provide magnetically optimized solutions for most applications. Package types SO is an SOT-23 (1.1 mm nominal height), package UA is a three-lead ultra-mini SIP for through-hole mounting.
