GENERAL DESCRIPTION
The ADXL206 is a precision, low power, complete dual-axis
iMEMS® accelerometer for use in high temperature environ-
ments. The accelerometer integrates the sensor with signal
conditioned voltage outputs on a single, monolithic IC.
The ADXL206 measures acceleration with a full-scale range
of ±5 g. The ADXL206 can measure both dynamic acceleration
(for example, vibration) and static acceleration (for example,
gravity).
The typical noise floor is 110 μg/√Hz, allowing signals below
1 mg (0.06° of inclination) to be resolved in tilt sensing appli-
cations using narrow bandwidths (<60 Hz).
The user selects the bandwidth of the accelerometer using
Capacitors CX and CY at the XOUT and YOUT pins, respectively.
Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the
application.
The ADXL206 is available in a 13 mm × 8 mm × 2 mm, 8-lead,
side-brazed ceramic dual in-line package (SBDIP).
