The MXD2125G/H/M/N is a low cost, dual axis accelerometer fabricated on a standard, submicron CMOS
process. It is a complete sensing system with on-chip mixed mode signal processing. The MXD2125G/H/M/N
measures acceleration with a full-scale range of ±3 g and a sensitivity of 12.5%/g @5V at 25°C. It can measure both
dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity).
The MXD2125G/H/M/N design is based on heat convection and requires no solid proof mass.
This eliminates stiction and particle problems associated with competitive devices and provides shock survival of 50,000
g, leading to significantly lower failure rate and lower loss due to handling during assembly.
The MXD2125G/H/M/N provides two digital outputs that are set to 50% duty cycle at zero g acceleration.
The outputs are digital with duty cycles (ratio of pulse width to period) that are proportional to acceleration. The duty
cycle outputs can be directly interfaced to a microprocessor.
The typical noise floor is 0.2 mg/ Hz allowing signals below 1 milli-g to be resolved at 1 Hz bandwidth.
The MXD2125G/H/M/N is packaged in a hermetically sealed LCC surface mount package (5 mm x 5 mm x 2 mm height)
and is operational over a -40°C to 105°C(M/N) and 0°C to 70°C(G/H) temperature range.
