Powerful Sensing Solutions for a Better Life
CXLTG-Series
HIGH PERFORMANCE ACCELEROMETER
The TG-Series 3-Axis accelerometers are high
performance ±2g and ±10g sensors, featuring
precision three-layer silicon differential capacitive
MEMS sensing elements that provide ultra low
noise and excellent stability. The TG-Series sensors
are fully signal conditioned and factory calibrated.
The single-ended high level analog outputs do not
require external signal conditioning and are easy to
interface to standard data acquisition systems.
Features
• Range: ±2g or ±10g
• High Stability
• Low Noise: 20µg/√Hz
Platform Leveling
Automotive Testing
• Low Power <10mW
The TG-Series operates on a single DC supply from 3.3 V to 5.5 V
and includes a high performance integrated temperature sensor
for additional accuracy under extreme temperature applications.
The typical current consumption of 1.5mA makes this triaxial
device attractive for battery operated systems.The sensor is packaged
in an industrial anodized aluminum package that is moisture
resistant and rugged for industrial and automotive applications.

Notes1 After temperature compensation by user. 2 Cross-axis sensitivity is the output response to acceleration in the orthogonal axes.3 Non-linearity is
the deviation of the output from a best fit straight line over fullscale input range All values are specified at operation voltage of 5.0V and temperature of
25ºC unless noted otherwise.4 Sensitivity and Zero g Output are ratiometric to supply voltage.
