datasheet for P15A by Advanced Hall Sensors Ltd.
AHS
P15A Hall Sensor (1000V/AT)
The P15A Hall Sensor is outstanding for its ultra-high
sensitivity and its low temperature coefficients.
AHS
The P15A Hall Sensor is fabricated from an
AlGaAs/InGaAs/GaAs 2 - DEG (two dimensional electron
gas) heterostructure.
