Hall-Effect Sensors Operate At Temperatures Up To 150°C

High stability in the face of extreme temperatures and stresses is featured in a family of chopper-stabilized, Hall-effect switches and latches. The A3240 switch and A3280 latch are designed to operate at temperatures up to 150°C. Their performance is enabled by a patented chopper-stabilization technique that reduces offset drift caused by temperature and stress and that allows for extremely sensitive switch points.The A3240 switch addresses industrial, automotive and other sensing applications, while the A3280 latch is aimed at motor commutation, speed sensing and direction detection applications.
