Specified Linear Range: Typically 70% of the field it takes to saturate the part. Field dependent

specifications are based upon this range.

TCOI (Temperature Coefficient of Output at Constant Input Current): The variation of the

output voltage over temperature with a constant input current applied. Expressed as a percentage per

unit temperature change.

TCOV (Temperature Coefficient of Output at Constant Input Voltage): The variation of the

output voltage over temperature with a constant input voltage applied. Expressed as a percentage per

unit temperature change.

TCR (Temperature Coefficient of Resistance):

The variation of the GMR resistors over

temperature. Expressed as a percentage per unit temperature change.

Voltage Span: The differential output voltage taken from zero to 70% of the saturation field level.
