General Description

The MXR6150G/M is an low noise and low profile, dual axis accelerometer fabricated on a standard, submicron CMOS process. It is a complete sensing system with on-chip mixed mode signal processing. The MXR6150G/M measures acceleration with a full-scale range of ±5 g and a sensitivity of 150mV/g @3V at 25°C. It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The MXR6150G/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 up to 50,000 g, leading to significantly lower failure rates and lower loss due to handling during assembly.

The MXR6150G/M provides two ratiometric analog outputs.

The maximum noise floor is 1 mg/ allowing signals below 1mg to be resolved at 1 Hz bandwidth. The MXR6150G/M is available in a hermetically sealed low profile LCC surface mount package (5mm x 5mm x 1.55mm). It is operational over a -40°C to 85°C (M) and 0°C to 70°C (G) temperature range.
