Low Cost ±1.2 g Dual Axis Accelerometer ADXL213 FEATURES GENERAL DESCRIPTION Dual axis accelerometer on a single IC chip The ADXL213 is a low cost, low power, complete dual axis 5 mm × 5 mm × 2 mm LCC package accelerometer with signal conditioned, duty cycle modulated 1 mg resolution at 60 Hz outputs, all on a single monolithic IC. The ADXL213 measures Low power: 700 µA at VS = 5 V (typical) acceleration with a full-scale range of ±1.2 g (typical). The High zero g bias stability ADXL213 can measure both dynamic acceleration (e.g., High sensitivity accuracy vibration) and static acceleration (e.g., gravity). Pulse width modulated digital outputs X and Y axes aligned to within 0.1° (typical) The outputs are digital signals whose duty cycles (ratio of pulse BW adjustment with a single capacitor width to period) are proportional to acceleration (30%/g). The Single-supply operation duty cycle outputs can be directly measured by a microcontrol- 3500 g shock survival ler without an A/D converter or glue logic. Innovative design techniques are used to ensure high zero g bias APPLICATIONS stability (typically better than 0.25 mg/°C), as well as tight sensi- Automotive tilt alarms tivity stability (typically better than 50 ppm/°C). Data projectors Navigation The typical noise floor is 160 µg/Hz, allowing signals below Platform stabilization/leveling 1 mg (0.06° of inclination) to be resolved in tilt sensing applica- Alarms and motion detectors tions using narrow bandwidths (<60 Hz). High accuracy, 2-axis tilt sensing The user selects the bandwidth of the accelerometer using capacitors CX and CY at the XFILT and YFILT pins. Bandwidths of 0.5 Hz to 250 Hz may be selected to suit the application. The ADXL213 is available in a 5 mm × 5 mm × 2 mm, 8-pad hermetic LCC package.
