Precision 1.7 g, 5 g, 18 g Single-/ Dual-Axis iMEMS Accelerometer Data Sheet ADXL103/ADXL203 FEATURES GENERAL DESCRIPTION High performance, single-/dual-axis accelerometer on The ADXL103/ADXL203 are high precision, low power, complete a single IC chip single- and dual-axis accelerometers with signal conditioned 5 mm 5 mm 2 mm LCC package voltage outputs, all on a single, monolithic IC. The ADXL103/ 1 mg resolution at 60 Hz ADXL203 measure acceleration with a full-scale range of 1.7 g, Low power: 700 A at V = 5 V (typical) S 5 g, or 18 g. The ADXL103/ADXL203 can measure both High zero g bias stability dynamic acceleration (for example, vibration) and static High sensitivity accuracy acceleration (for example, gravity). 40C to +125C temperature range The typical noise floor is 110 g/Hz, allowing signals below 1 mg X and Y axes aligned to within 0.1 (typical) (0.06 of inclination) to be resolved in tilt sensing applications Bandwidth adjustment with a single capacitor using narrow bandwidths (<60 Hz). Single-supply operation The user selects the bandwidth of the accelerometer using 3500 g shock survival Capacitor CX and Capacitor CY at the XOUT and YOUT pins. RoHS compliant Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the Compatible with Sn/Pb- and Pb-free solder processes application. Qualified for automotive applications The ADXL103 and ADXL203 are available in a 5 mm 5 mm 2 mm, 8-terminal ceramic LCC package.
