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.

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.

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.
