A1121 - Chopper-Stabilized Precision Hall-Effect Switches

General Description

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.

Key Features

  • AEC-Q100 automotive qualified.
  • Unipolar switch points.
  • Resistant to physical stress.
  • Superior temperature stability.
  • Output short-circuit protection.
  • Operation from unregulated supply.
  • Reverse-battery protection.
  • Solid-state reliability.
  • Small package sizes.
