NVE ADL021-14E

ADLxxx - Series sensors are Giant Magnetoresistive (GMR) Digital Switch devices designed to operate from 3 - volt power supplies or single lithium cells with extremely supply low currents. The devices are manufactured with NVE's patented spintronic GMR technology and low - power CMOS circuitry for unmatched miniaturization, sensitivity, precision, and low power. The output is configured as a magnetic "switch" where the output turns on when the magnetic field is applied, and turns off when the field is removed. Versions are available that are either continuous duty or internally duty cycled operation to further reduce power consumption. An integrated latch ensures the output is available continuously in duty - cycled versions. The applied field can be of either polarity, and the operate point is extremely stable over supply voltage and temperature. The output is current - sinking, and can sink up to 100 microamps.
