GENERAL DESCRIPTION

The MXR2500MW provides two absolute analog outputs.

The MXR2500MW is an ultra low noise and 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 MXR2500MW

measures acceleration with a full-scale range of 2 g and a

sensitivity of 500mV/g @5V at 25C. It can measure both

dynamic acceleration (e.g., vibration) and static

acceleration (e.g., gravity). The MXR2500MW 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 rates and

lower loss due to handling during assembly.

The typical noise floor is 0.2 mg/

allowing signals

below 1 mg to be resolved at 1 Hz bandwidth. The 3dB

rolloff of the device occurs at 17 Hz. The MXR2500MW is

available in a LCC surface mount package (5.5 mm x 5.5

mm x 2.7 mm). It is hermetically sealed and is operational

over a -40C to +105C temperature range. It also contains

an on-chip temperature sensor and a bandgap voltage

reference.
