Description
The A3280, A3281, and A3283 Hall-effect latches are ex treme ly temperature-stable and stress-resistant sensor ICs 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.
