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 VDD.

Note 7: Programming of the EEPROM at room temperature is recommended.

Note 8: Allow a minimum of 6ms elapsed time before sending any command.
