STMicroelectronics AIS1200DS
The AIS1200DS is a satellite acceleration sensor ro with a single-axis sensing element and an IC interface capable of providing acceleration P information to external applications through a te 225 kbps DSI 2.02 interface. 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. SO16W The AIS1200DS acquisition chain is composed of a C/V converter, a full-differential charge amplifier, a 1st-order LPF @ 1.6 KHz, a 3rd-order LP Bessel filter @ 360 Hz and a second charge amplifier to adapt the dynamic range to SAR A/D converter input.
