  • The AIS1120SX / AIS2120SX is a central acceleration sensor with a single or dual axis sensing element and an IC interface able to provide acceleration information to a master control unit via an SPI protocol.

    The sensing element, capable of detecting the acceleration, is manufactured using a dedicated process developed by ST to produce inertial sensors and actuators in silicon.
    The IC interface is manufactured using a BCD process that allows a high level of integration. The device is factory trimmed to better tune the characteristics of the sensing element with the acceleration information to be supplied.
    The AIS1120SX / AIS2120SX has a full scale of ±120 g. The acquisition chain consists of a C/V converter, a full-differential charge amplifier, a 2nd order ΣΔ analog-to-digital converter and a digital core, which includes filtering, compensation and interpolation, control logic and SPI protocol generation.
    The differential capacitance of the sensor is proportional to the proof mass displacement; thus, by sensing the differential capacitance, the position of the sensor is determined. Then, since the mass position is known, and the position is related to the input acceleration, the input acceleration can be easily deduced.
    The device is available in a plastic SOIC8 package and is guaranteed to operate over a temperature range extending from -40 °C to +105 °C.
