A1221LUA-T, Board Mount Hall Effect / Magnetic Sensors CHOPPER-STABILIZED PRECISION HALL EFFECT LATCH
Sensors\Magnetic Sensors\Board Mount Hall Effect / Magnetic Sensors
The A1221LUA-T is a Hall-effect Sensor IC is extremely temperature-stable and stress-resistant device 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 overmolding, temperature dependencies and thermal stress. Each device includes on a single silicon chip a voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger and a short-circuit protected open-drain output to sink up to 25mA. A south pole of sufficient strength turns the output on. A north pole of sufficient strength is necessary to turn the output off. An on board regulator permits operation with supply voltages of 3 to 24V.
