Micropower Omnipolar Digital Hall-effect Sensor ICs SL353 Series Datasheet
Micropower Omnipolar Digital Hall-effect Sensor ICs Micropower Omnipolar Digital Hall-effect Sensor ICs, SL353 Series, are small, and versatile, digital Hall-effect devices operated by the magnetic field from a permanent magnet or an electromagnet. These sensitive devices are designed to meet a wide range of potential applications with low power requirements including battery-operated equipment.
Features and Benefits Versatile Omnipolar capability with high-duty and low-duty cycle options allows for use in a variety of potential applications with low power requirements and/or battery operations. Stable Thermally balanced integrated circuit provides for stable operation over a wide temperature range, from -40 °C to 85 °C [-40 °F to 185 °F].
