GENERAL D ESCRIP TIO N  
T he AD22151 is a linear magnetic field transducer. T he sensor  
output is a voltage proportional to a magnetic field applied  
perpendicularly to the package top surface.  
NC  
R1  
R2  
T he sensor combines integrated bulk Hall cell technology and  
instrumentation circuitry to minimize temperature related drifts  
associated with silicon Hall cell characteristics. T he architecture  
maximizes the advantages of a monolithic implementation while  
allowing sufficient versatility to meet varied application require-  
ments with a minimum number of components.

OUTPUT  
Principle features include dynamic offset drift cancellation and a  
built-in temperature sensor. Designed for single +5 volt supply  
operation, the AD22151 achieves low drift offset and gain op-  
eration over –40°C to +150°C. T emperature compensation can  
accommodate a number of magnetic materials commonly uti-  
lized in economic position sensor assemblies.

T he transducer may be configured for specific signal gains de-  
pendent upon application requirements. Output voltage can be  
adjusted from fully bipolar (reversible) field operation to fully  
unipolar field sensing.

T he voltage output achieves near rail-to-rail dynamic range,  
capable of supplying 1 mA into large capacitive loads. T he sig-  
nal is ratiometric to the positive supply rail in all configurations.
