4301 - UGN3503U Hall Effect Sensor

"The UGN3503U Hall-effect sensor accurately track extremely small changes in magnetic flux density-changes generally too small to operate Hall-effect switches. As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of electromagnets, they can effectively measure a system's performance with negligible system loading while providing isolation from contaminated and electrically noisy environments. Each Hall-effect integrated circuit includes a Hall sensing element, linear amplifier, and emitter-follower output stage. Problems associated with handling tiny analog signals are minimized by having the Hall cell and amplifier on a single chip. Extremely Sensitive Flat Response to 23 kHz Low-Noise Output 4.5 V to 6 V Operation Magnetically Optimized Package "
