Smal , Low Power, 3-Axis ±200 g Accelerometer Data Sheet ADXL377 FEATURES GENERAL DESCRIPTION 3-axis sensing
The ADXL377 is a small, thin, low power, complete 3-axis
Small, low profile package
accelerometer with signal conditioned voltage outputs. The
3 mm × 3 mm × 1.45 mm LFCSP
ADXL377 measures acceleration resulting from motion, shock,
Low power: 300 µA (typical)
or vibration with a typical full-scale range of ±200 g.
Single-supply operation: 1.8 V to 3.6 V
The user selects the bandwidth of the accelerometer using
10,000 g shock survival
the C
Excellent temperature stability
X, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins. Bandwidths can be selected to suit the application, with a range
Bandwidth adjustment with a single capacitor per axis
of 0.5 Hz to 1300 Hz for the x-axis and y-axis and a range of
RoHS/WEEE and lead-free compliant
0.5 Hz to 1000 Hz for the z-axis.
APPLICATIONS
The ADXL377 is available in a smal , low profile, 3 mm × 3 mm ×
Concussion and head trauma detection
1.45 mm, 16-lead lead frame chip scale package (LFCSP_LQ).
