FEATURES 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 Ro HS/WEEE and lead-free pliant APPLICATIONS Concussion and head trauma detection High force event detection Small, Low Power, 3-Axis ±200 g Accelerometer ADXL377 GENERAL DESCRIPTION The ADXL377 is a small, thin, low power, plete 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 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. 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).
