MXR9150MZ Evaluation Board

MXR9150MZ-B Evaluation Board for the MXR9150MZ ±5 g Tri Axis Accelerometer with Ratiometric Outputs

Memsic Inc.

The MXR9150G/M is a tri axis accelerometer fabricated on a standard, submicron CMOS process. It is a complete sensing system with on-chip mixed signal processing. The MXR9150G/M measures acceleration with a full-scale range of ±5.0 g and a sensitivity of 150mV/g @3.0V at 25°C. It can measure both dynamic acceleration (e.g. vibration) and static acceleration (e.g. gravity).

Product Description

The MXR9150G/M 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 greater than 50,000 g, leading to significantly lower failure rate and lower loss due to handling during PCB assembly and at customer field application.

The MXR9150G/M provides three ratiometric analog outputs that are set to 50% of the power supply voltage at zero g.

The Max. noise floor is 1 mg / √Hz allowing signals below 1mg to be resolved at 1 Hz bandwidth. The MXR9150G/M is packaged in a hermetically sealed, surface mount LCC 16 pins package (7 mm × 7 mm × 1.8 mm height) and is operational over a -40°C to +85°C (M) and 0°C to +70°C (G) temperature range.
