LIN 2.1 compliant interface (bridge sensor signal, temperature)
Digitally programmable gain and offset voltage adjustment
Gain range from 2.94 V/V to 971.10 V/V
Sensor temperature compensation (first- or second-order)
Sensor nonlinearity correction (first- or second-order)
Internal or external temperature sensor compensation
EEPROM nonvolatile memory for calibration data
High system accuracy: 0.1% FSR over temperature
EMC and EMI protection
Fault protection for open circuits and short circuits
4 mm × 4 mm, 20-lead LFCSP
6 V to 18 V supply operation
−40°C to +150°C operating temperature range
AEC-Q100 qualified for automotive applications
APPLICATIONS
Strain gage
Pressure signal conditioner for automotive vehicles
