Description: A1120, A1121, A1122, and A1125 Chopper Stabilized Precision Hall Effect Switch es Features and Benefits ▪ ▪ ▪ ▪ ▪ ▪ ▪ Unipolar switchpoints Resistant to physical stress Superior temperature stability Output short-circ uit protection Operation from unregulat ed supply Reverse battery protection So lid-state reliability Small package siz es Description The A1120, A1121, A1122 , and A1125 Hall-effect, unipolar switc hes are extremely temperature-stable an d stress-resistant sensor ICs, especial ly suited for operation over extended t emperature ranges to 150°C. Superior h igh-temperature performance is made pos sible through dynamic offset cancellati on, which reduces the residual offset voltage normall
