It is a complete sensing system with on-chip mixed mode signal processing. The MXD2020GL/HL/ML/NL measures acceleration with a full-scale range of ±1 g and a sensitivity of 20%/g. It can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity). The MXD2020GL/HL/ML/NL design is based on heat convection and requires no solid proof mass. This eliminates stiction and particle problems associated with c...
