MXD2002A/B FUNCTIONAL BLOCK DIAGRAM
The MXD2002A/B is a very low cost, dual axis accelerometer fabricated on a standard, submicron CMOS process. The MXD2002A/B measures acceleration with a full-scale range of ±10 g. (The MEMSIC accelerometer product line extends from ±1 g to ±10 g with custom versions available above ±10 g.) It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The MXD2002A/B design is based on heat convection and requires no solid...
