2-WIRE, CHOPPER-STABILIZED,  
HALL-EFFECT SWITCHES  
The A3361x and A3362x Hall-effect switches are extremely  
temperature-stable and stress-resistant sensors. Superior performance  
over temperature is made possible through dynamic offset cancellation,  
which reduces the residual offset voltage normally caused by device  
overmolding, temperature dependencies, and thermal stress. The two  
devices differ only in output polarity; the A3361x output current goes  
low in the presence of a south pole of sufficient strength; the A3362x  
output current goes high.  
Suffix Code 'LH' Pinning

Each device includes on a single silicon chip a voltage regulator,  
Hall-voltage generator, small-signal amplifier, chopper stabilization,  
Schmitt trigger, and a constant-current open-collector output. An  
on-board regulator permits operation with supply voltages of 3.5 to 24  
volts. Noise radiation is limited by control of the output current slew  
rate.

Three package styles provide a magnetically optimized package for  
most applications. Suffix ‘xLH’ is a miniature low-profile surface-  
mount package, ‘xLT’ is a miniature SOT-89/TO-243AA transistor  
package for surface-mount applications; while suffix ‘xUA’ is a three-  
lead ultra-mini-SIP for through-hole mounting.
