Note 1:
Contact factory for high-volume applications requiring less than 1.5mA.
Note 2:
All electronics temperature errors are compensated together with the sensor errors.
Note 3:
The sensor and the MAX1450 must always be at the same temperature during calibration and use.
Note 4:
This is the maximum allowable sensor offset at minimum gain (39V/V).
Note 5:
This is the sensor’s sensitivity normalized to its drive voltage, assuming a desired full-span output (FSO) of 4V and a bridge
voltage of 2.5V. Operating at lower bridge excitation voltages can accommodate higher sensitivities.
