A1120, A1121, A1122, and A1125  
Chopper Stabilized Precision Hall Effect Switches  
Features and Benefits  
Description  
Unipolar switchpoints  
The A1120, A1121, A1122, 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. Superior high-temperature  
performance is made possible through dynamic offset  
cancellation,whichreducestheresidualoffsetvoltagenormally  
causedbydeviceovermolding,temperaturedependencies,and  
thermal stress.  
Resistant to physical stress  
Superior temperature stability  
Output short-circuit protection  
Operation from unregulated supply  
Reverse battery protection  
Solid-state reliability  
Small package sizes  
Eachdeviceincludesonasinglesiliconchipavoltageregulator,  
Hall-voltage generator, small-signal amplifier, chopper  
stabilization, Schmitt trigger, and a short-circuit protected  
open-drain output to sink up to 25 mA.  
Packages:  
An on-board regulator permits operation with supply voltages  
of 3 to 24 V. The advantage of operating down to 3 V is that  
the device can be used in 3 V applications or with additional  
external resistance in series with the supply pin for greater  
protection against high voltage transient events.  
For the A1120, A1121, and A1122, a south pole of sufficient  
strength turns the output on. Removal of the magnetic field  
turns the output off. The A1125 is complementary, in that for  
these devices, a south pole turns the A1125 output off, and  
removal of the magnetic field turns the output on.
