The ADXL311 is built using the same proven iMEMS® process used in over 100 million Analog Devices accelerometers shipped to date, with demonstrated 1 FIT reliability (1 failure per 1 billion device operating hours). The ADXL311 will measure acceleration with a full-scale range of ±2 g. The ADXL311 can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity). The outputs are analog voltages proportional to acceleration. The typical noise floor is 300 µ g/√Hz allowing signals below 2 m g (0.1° of inclination) to be resolved in tilt sensing appli- cations using narrow bandwidths (10 Hz). The user selects the bandwidth of the accelerometer using capacitors CX and CY at the XFILT and YFILT pins. Bandwidths of 1 Hz to 2 kHz may be selected to suit the application. The ADXL311 is available in a 5 mm × 5 mm × 2 mm 8-terminal hermetic CLCC package COM YOUT XOUT VDD CX ADXL311JE Y SENSOR 3.0V SELF TEST X SENSOR RFILT 32k Ω RFILT 32k Ω 200k Ω CY CDC OSCILLATOR DEMOD DEMOD BIAS Figure 1.
