GENERAL DESCRIPTION  
NC  
R1  
The AD22151 is a linear magnetic field transducer. The sensor  
output is a voltage proportional to a magnetic field applied  
perpendicularly to the package top surface.  
R2  
0.1F  
The sensor combines integrated bulk Hall cell technology and  
instrumentation circuitry to minimize temperature related drifts  
associated with silicon Hall cell characteristics. The architecture  
maximizes the advantages of a monolithic implementation while  
allowing sufficient versatility to meet varied application require-  
ments with a minimum number of components.

Principal features include dynamic offset drift cancellation  
and a built-in temperature sensor. Designed for single 5 V  
supply operation, the AD22151 achieves low drift offset and  
gain operation over –40C to +150C. Temperature compensa-  
tion can accommodate a number of magnetic materials commonly  
utilized in economic position sensor assemblies.

R1  
The transducer can be configured for specific signal gains to  
meet various application requirements. Output voltage can be  
adjusted from fully bipolar (reversible) field operation to fully  
unipolar field sensing.

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