Data Sheet Precision ±1.7 g, ±5 g, ±18 g Single-/ Dual-Axis iMEMS® Accelerometer ADXL103/ADXL203 FEATURES High performance, single-/dual-axis accelerometer on a single IC chip 5 mm × 5 mm × 2 mm LCC package 1 mg resolution at 60 Hz Low power: 700 µA at VS = 5 V (typical) High zero g bias stability High sensitivity accuracy −40°C to +125°C temperature range X and Y axes aligned to within 0.1° (typical) Bandwidth adjustment with a single capacitor Single-supply operation 3500 g shock survival RoHS compliant Compatible with Sn/Pb- and Pb-free solder processes Qualified for automotive applications APPLICATIONS Vehicle dynamic controls Electronic chassis controls Platform stabilization/leveling Navigation Alarms and motion detectors High accuracy, 2-axis tilt sensing Vibration monitoring and compensation Abuse event detection GENERAL DESCRIPTION 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 ±1.7 g, ±5 g, or ±18 g. The ADXL103/ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity). The typical noise floor is 110 µg/√Hz, allowing signals below 1 mg (0.06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<60 Hz). The user selects the bandwidth of the accelerometer using Capacitor CX and Capacit...
