A1121 Chopper-Stabilized Precision Hall-Effect Switches

The A1120, A1121, A1122, A1123, and A1125 Hall-effect unipolar switches are extremely temperature-stable and stress-resistant sensor ICs, especially suited for operation over extended temperature ranges to 150°C. Superior hightemperature performance is made possible through dynamic offset cancellati.
