A3281LT中文资料ALLEGRO数据手册PDF规格书

The A3280--, A3281--, and A3283-- Hall-effect latches are ex tremely temperature-stable and stress-resistant sensors especially suited for operation over extended temperature ranges to +150°C. Superior high-temperature per for mance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device overmolding, temperature dependencies, and thermal stress. The three devices are iden ti cal except for mag net ic switch points.
