Low-g Range Accelerometer Series
Page 1 of 1
A dedicated product family of low-g range accelerometer chips and modules is designed to support a variety of zero-to-medium frequency aerospace, automotive, defense, energy, industrial and general test & measurement requirements. The LG Series from Silicon Designs provides high-drive, low-impedance buffering for high-reliability performance in temperatures up to 125°C within a rugged, anodized aluminum housing.
The LG Series accelerometer modules produce two analog voltage outputs which vary with acceleration and feature a four-wire connection in support of both single-ended and differential modes. The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as applied force to the bottom of the package. Signal outputs are fully differential about a common mode voltage of approximately 2.5V and may be powered with a 9V battery. Sensitivity is independent from the +8 to +32V supply voltage. At zero acceleration, output differential voltage is nominally 0 VDC and ±4 VDC at full-scale acceleration. On-board voltage regulation and an internal voltage reference eliminate precision power supply requirements. The LG Series is also relatively insensitive to temperature changes with quick, easy self-calibration.
