A3340  
Chopper-Stabilized, Precision  
Hall-Effect Switch  
Features and Benefits  
Resistant to physical stress  
Superior temperature stability  
Output short-circuit protection  
Operation from unregulated supply  
Reverse battery protection  
Solid-state reliability  
Description  
TheA3340Halleffectswitchisanextremelytemperature-stable  
and stress-resistant sensor especially suited for operation  
over extended temperature ranges up 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.  
Small size  
Thedeviceincludesonasinglesiliconchipavoltageregulator,  
Hall-voltage generator, small-signal amplifier, chopper  
stabilization, Schmitt trigger, and a short-circuit protected  
open-collector output to sink up to 25 mA. A south pole of  
sufficientstrengthwillturntheoutputoff.Anon-boardregulator  
permits operation with supply voltages of 4.2 to 24 volts.  
Twopackagestylesprovideamagneticallyoptimizedpackage  
for most applications. Suffix LH is an SOT23Wsurface mount  
package and while suffix UA is a three-lead ultramini SIP for  
through hole mounting.  
Packages: 3 pin SOT23W (suffix LH),  
and 3 pin SIP (suffix UA)  
The A3340 complements the A3240, which offers the same  
features, but with the opposite output polarity.
