ADXL316
GENERAL DESCRIPTION
The ADXL316 is a small, thin, low power, complete 3-axis
accelerometer with signal conditioned voltage outputs, all on a
single monolithic IC. The product measures acceleration with a
minimum measurement range of ±16 g. It can measure the
static acceleration of gravity in tilt sensing applications, as well
as dynamic acceleration resulting from motion, shock, or
vibration.
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 1600 Hz for the x and y axes, and a range
of 0.5 Hz to 550 Hz for the z axis.
The ADXL316 is available in a small, low profile, 4 mm × 4 mm ×
1.45 mm, 12-lead, plastic lead frame chip scale package (LFCSP).
