ADXL377
GENERAL DESCRIPTION
The ADXL377 is a small, thin, low power, complete 3-axis
accelerometer with signal conditioned voltage outputs. The
ADXL377 measures acceleration resulting from motion, shock,
or vibration with a typical full-scale range of ±200 g.
The user selects the bandwidth of the accelerometer using
the C_X, C_Y, and C_Z capacitors at the X_OUT, Y_OUT, and Z_OUT pins.
Bandwidths can be selected to suit the application, with a range
of 0.5 Hz to 1300 Hz for the x-axis and y-axis and a range of
0.5 Hz to 1000 Hz for the z-axis.
The ADXL377 is available in a small, low profile, 3 mm × 3 mm ×
1.45 mm, 16-lead lead frame chip scale package (LFCSP_LQ).
