The UGN3503LT, UGN3503U, and UGN3503UA Hall-effect sensor ICs accurately track extremely small changes in magnetic flux density—changes generally too small to operate Hall-effect switches.
For 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 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.
Three package styles provide a magnetically optimized package for most applications. Package suffix ‘LT’ is a miniature SOT-89/TO243AA transistor package for surface-mount applications; suffix ‘U’ is a miniature three-lead plastic SIP, while ‘UA’ is a three-lead ultra-miniSIP. All devices are rated for continuous operation over the temperature range of -20°C to +85°C.
