NSA9260 (X) is an EMC enhanced AECQ100 compliant high integration chip for signal conditioning of resistance bridge automotive pressure sensors. The NSA9260 (X) adopts a high-precision variable gain instrument amplifier and a 24-bit ADC to form the main signal measurement channel, and a 24-bit ADC to form the auxiliary temperature measurement channel. With built-in digital processing engine, the NSA9260X supports second-order temperature drift calibration and the highest third-order nonlinear calibration for sensor zero temperature and sensitivity of the sensor. Its calibration coefficients are stored in a set of programmable EEPROMs. NSA9260X supports over-voltage and reverse-voltage protection, analog voltage output and PWM output, as well as sensor diagnosis.
