WSH136 Linear Hall Effect Sensor IC Features: Wide operating range 3.0~12V, -40℃~125℃ Flat Response to 23kHz High Sensitivity 3.0mV/G Wide sensible magnetic field range on different supplied voltage ±600 Gauss on 5V supplied voltage ±1500 Gauss on 12V supplied voltage. Low operating current 3mA Two package styles TO-92S/SOT-23 available. Built-in temperature compensated circuit to minimize temperature’s effect Functional Description : The W136 integrates Hall sensing element, linear amplifer, sensitivity controller and emitter follower output stage.It accurately tracks extremely small change in magnetic flux density –generally too small to operate Hall effect switch. W136 can be applied as current sensor, tooth sensor, proximity detectors and motion detectors. As sensitive monitor of magnetic flux, it can effectively measure a system’s performance with negligible system loading while providing isolation from contaminated and electrically noisy environments.
