With the increasing need for faster data transfer rates, the transition from electrical to optical signaling in data processing is inevitable. Copper cabling cannot keep up with the upcoming data center bandwidth requirements, for applications such as multimedia streaming and high performance computing. One technology that could enable true optical communication is silicon photonics. read more…
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.
