Automotive Bridge Sensor Conditioner Based on NSC9260 Application Note
■The NSC9260 is a highly integrated and AEC-Q100 qualified IC for capacitive sensor conditioning.
■The NSC9260 integrates an instrumentation PGA, a 24-bit ADC for primary signal measurement channel, a 24-bit ADC for temperature measurement channel and sensor calibration logic. With the calibration algorithm built in the internal MCU, the NSC9260 supports to compensate sensor offset, sensitivity, temperature drift up to 2 nd order, and non-linearity up to the 3 rd order. The calibration coefficients are stored in a 64-Byte EEPROM that can be programmed multiple times.
■The NSC9260 also supports Over-voltage and Reverse-voltage protection. It can provide analog Moutput and PWM output. It can also support sensor diagnosis.
