Product Description

ASIC functions

§ Offset Calibration: Calibration of capacitive sensor offset

§ Span Calibration Calibration of capacitive sensor span

§ Self test of ASIC(Build in switch capacitance circuit to test the ASIC)

§ Self test of sensor(by applying a voltage to the capacitive accelerometer, the self test function test the integrity of the sensor during field operation

§ Bandwidth adjustment (low pass 500Hz or 2000Hz), 50Hz with external capacitor

§ Clock Frequency adjustment
