Signal Conditioning Chip for Capacitive Automobile Pressure Sensor

•  Support -24V to 28V over voltage and reverse voltage protection for automotive sensor applications

•  It integrates C/V capacitive voltage conversion circuit and 24-bit high-precision ADC, which can easily measure capacitance of capacitive pressure sensor, calculate and convert it to pressure.

•  Built-in digital processor-based sensor calibration logic, supporting post-customer calibration, up to third-order nonlinear calibration and second-order temperature sensitivity and offset calibration

•  Calibration data can be stored in EEPROM, multiple times programmable

•  Ratio-metric or absolute voltage output, supporting PWM output

•  Enhanced EMC performance

•  Proprietary OWI communication mode, supporting calibration after sensor assembly

•  Operating temperature range: -40℃ ~ 150℃, compatible with AECQ100 standard

•  Auto capacitive pressure sensor module (automotive air conditioning pressure, brake pressure, etc.)
