The MXA2500ML 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 MXA2500GL/ML measures acceleration with a full-scale range of 1g and a sensitivity of 500mV/g. It can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity).

The MXA2500ML 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 MXA2500ML provides two absolute outputs that are set to 1.25V at zero g acceleration.

The typical noise floor is 0.2 mg/ allowing signals below 1 milli-g to be resolved at 1 Hz bandwidth. The MXA2500ML is packaged in a hermetically sealed LCC surface mount package (5 mm x 5 mm x 2 mm height) and is operational over a -40C to 85C temperature range. Click here for datasheet.
