ADI ADXL203CE

The ADXL103/ADXL203 are high precision, low power, complete single- and dual- axis accelerometers with signal conditioned voltage outputs, all on a single, monolithic IC. The ADXL103/ADXL203 measure acceleration with a full- scale range of ± 1.7g, ± 5g, or ± 18g. The ADXL103/ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity). The typical noise floor is 110μg / √Hz allowing signals below 1mg (0.06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (< 60Hz). The user selects the bandwidth of the accelerometer using Capacitor C_X and Capacitor C_Y at the X_OUT and Y_OUT pins. Bandwidths of 0.5Hz to 2.5kHz can be selected to suit the application. The ADXL103 and ADXL203 are available in a 5mm×5mm×2mm 8- terminal ceramic LCC package.
