A3211 and A3212  
Micropower, Ultra-sensitive  
Hall-effect Switches  
Features and Benefits  
Micropower operation  
Operation with north or south pole  
2.5 to 3.5 V battery operation  
Chopper stabilized  
Superior temperature stability  
Extremely low switchpoint drift  
Insensitive to physical stress  
High ESD protection  
Description  
The A 3211 and A3212 integrated circuits are ultra-sensitive,  
pole independent Hall-effect switches with latched digital  
output. These sensors are especially suited for operation in  
battery-operated, hand-held equipment such as cellular and  
cordless telephones, pagers, and palmtop computers. A 2.5  
volt to 3.5 volt operation and a unique clocking scheme reduce  
the average operating power requirements to less than 15 μW  
with a 2.75 volt supply.  
Solid-state reliability  
Small size  
Easily manufacturable with magnet pole independence  
Unlike other Hall-effect switches, either a north or south pole  
of sufficient strength will turn the output on in the A3212,  
and in the absence of a magnetic field, the output is off. The  
A3211providesaninvertedoutput.Thepolarityindependence  
and minimal power requirements allow these devices to easily  
replace reed switches for superior reliability and ease of  
manufacturing, while eliminating the requirement for signal  
conditioning.  
Packages:  
Improved stability is made possible through chopper  
stabilization (dynamic offset cancellation), which reduces the  
residualoffsetvoltagenormallycausedbydeviceovermolding,  
temperature dependencies, and thermal stress.
