Silicon Designs rolls out ±5-g MEMS accelerometer

Silicon Designs Inc. – Joining Silicon Designs’ 2210 series of single-axis accelerometer modules is a ±5-g model intended to support a variety of lower-frequency aerospace, automotive, defense, industrial, and general test and measurement requirements. The 2210-005 incorporates MEMS capacitive sensing elements packaged within a lightweight anodized epoxy-sealed aluminum housing that occupies a total footprint of just 1 square in.

The accelerometer has a simple four-wire connection and internal voltage regulator to minimize supply-voltage variation effects. It is relatively insensitive to temperature changes and features high-drive, low-impedance buffering to support low-frequency acceleration measurement requirements from DC to 400 Hz.

All models in the 2210 series produce two analog voltage outputs, which vary with acceleration. You can choose either 0.5-V to 4.5-V single-ended or ±4-V differential output, which doubles the sensitivity over single-ended output. Differential sensitivity for the 2210-005 is 800 mV/g.

The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as a force pushing on the bottom of the package. Signal outputs are fully differential about a common-mode voltage of approximately 2.5 V. Output scale factor is independent from the supply voltage of +9 V to +32 V.
