A1122LUA-T

The A1122LUA-T is a through hole-mount chopper stabilized precision Hall Effect Switch with superior temperature stability. The A1120 unipolar switch is extremely temperature-stable and stress-resistant sensor IC, especially suited for operation over extended temperature ranges to 150°C. Superior high temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device over-moulding, temperature dependencies and thermal stress. An on-board regulator permits operation with supply voltage of 3 to 24V. The advantage of operating down to 3V is that the device can be used in 3V applications or with additional external resistance in series with the supply pin for greater protection against high voltage transient events.
