Product Overview
The SC4011 is a low-cost, compact linear Hall effect sensor IC designed for applications requiring precise magnetic field detection. It offers a single current source output with low noise, eliminating the need for external filtering. The sensor responds to both positive and negative magnetic fields, exhibits high resistance to mechanical stress, and operates across a wide ambient temperature range of -40C to 105C. Its output voltage is proportional to both the supply voltage and the sensed magnetic field strength. Available in TO-92S, SOT23-3L, and DFN1616 packages, the SC4011 is suitable for diverse applications including linear keyboards, motor control, position detection, current sensing, and weighing/level detection.
