ADXL323 Datasheet | Analog Devices

FEATURES 2-axis sensing Small, low-profile package 4 mm × 4 mm × 1.45 mm LFCSP_LQ Low power 180 μA at VS = 1.8 V (typical) Single-supply operation 1.8 V to 5.25 V 10,000 g shock survival Excellent temperature stability BW adjustment with a single capacitor per axis Ro HS/WEEE lead-free pliant GENERAL DESCRIPTION The ADXL323 is a small, thin, low power, plete 2-axis accelerometer with signal-conditioned voltage outputs, all on a single, monolithic IC. The product measures acceleration with a minimum full-scale range of ±3 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 CX and CY capacitors at the XOUT and YOUT pins. Bandwidths can be selected to suit the application, with a range of 0.5 Hz to 1600 Hz. The ADXL323 is available in a small, low profile, 4 mm × 4 mm × 1.45 mm, 16-lead, plastic lead frame chip scale package (LFCSP_LQ).
