_______________________________________________________________________________________
Note 1:
Excludes sensor or load current.
Note 2:
All electronics temperature errors are compensated together with sensors errors.
Note 3:
The sensor and the MAX1452 must be at the same temperature during calibration and use.
Note 4:
This is the maximum allowable sensor offset.
Note 5:
This is the sensor's sensitivity normalized to its drive voltage, assuming a desired full span output of +4V and a bridge volt-
age of +2.5V.
Note 6:
Bit weight is ratiometric to V
DD
.
Note 7:
Programming of the EEPROM at room temperature is recommended.
Note 8:
Allow a minimum of 6ms elapsed time before sending any command.
