MXD6125Q FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The MXD6125Q is a low noise, low profile, dual axis
accelerometer fabricated on a standard CMOS process. It is
a complete sensing system with on-chip mixed mode signal
processing. The MXD6125Q measures acceleration with a
full-scale range of ±1 g and a sensitivity of 12.5%/g @3V at
25°C. It can measure both dynamic acceleration (e.g.,
vibration) and static acceleration (e.g., gravity). The
MXD6125Q design is based on heat convection and requires
no solid proof mass. This eliminates stiction and particle
issues normally found with capacitive based technology, and
significantly lowers field failure rate and in-line loss due to
handling during assembly.
.
The MXD6125Q provides two digital outputs that are set to
50% duty cycle at zero g acceleration. The maximum noise
floor is 0.18 mg/ Hz allowing signals below 0.5 mg to be
resolved at 1 Hz bandwidth and the 3dB rolloff of the device
occurs at 8 Hz. The MXD6125Q is available in a
hermetically sealed low profile LCC surface mount package
measuring 5mm x 5mm x 1.55mm.
