HALL-EFFECT SENSOR ICS
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/TO-
243AA transistor package for surface-mount applications; suffix ‘U’ is a
miniature three-lead plastic SIP, while ‘UA’ is a three-lead ultra-mini-
SIP. All devices are rated for continuous operation over the temperature
range of -20°C to +85°C.
