Note 1: Excludes sensor or load current.
Note 2: This is the maximum allowable sensor offset.
Note 3: This is the sensor’s sensitivity normalized to its drive voltage, assuming a desired full-span output of 4V and a bridge voltage of 2.5V.
Note 4: Bit weight is ratiometric to V
Note 5: All units production tested at T
Note 6: Programming of the EEPROM at temperatures below +70°C is recommended.
Note 7: For operation above +70°C, limit erase/write cycle to 100.
Note 8: All erase commands require 7.1ms minimum time.
