±200 g Accelerometer
ADXL377 Data Sheet
FEATURES GENERAL DESCRIPTION 3-axis sensing
Small, low profile package
3 mm × 3 mm × 1.45 mm LFCSP
Low power: 300 µA (typical)
Single-supply operation: 1.8 V to 3.6 V
10,000 g shock survival
Excellent temperature stability
Bandwidth adjustment with a single capacitor per axis
RoHS/WEEE and lead-free compliant 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. APPLICATIONS 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). The user selects the bandwidth of the accelerometer using
the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT 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. Concussion and head trauma detection
