Pedometers and activity monitors Game controllers Toys and entertainment products GENERAL DESCRIPTION The ADXL311 is a low power, complete dual-axis accelerometer The typical noise floor is 300 µg/Hz, allowing signals below with signal conditioned voltage outputs, all on a single 2 mg (0.1° of inclination) to be resolved in tilt sensing appli- monolithic IC. The ADXL311 is built using the same proven cations using narrow bandwidths (10 Hz). iMEMS® process used in over 180 million Analog Devices accelerometers shipped to date, with demonstrated 1 FIT The user selects the bandwidth of the accelerometer using reliability (1 failure per 1 billion device operating hours). capacitors CX and CY at the XOUT and YOUT pins. Bandwidths of 1 Hz to 3 kHz can be selected to suit the application.
