Precision ±1.7 g, ±5 g, ±18 g Dual-Axis iMEMS® Accelerometer
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, ±18 g. The ADXL103/ADXL203 can measure both dynamic acceleration (for example, vibration) and static acceleration (for example, gravity).
A typical noise floor as low as 110 µg/√Hz, allows 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 Capacitor CY at the XOUT and YOUT pins. Bandwidths of 0.5 Hz to 2.5 kHz may be selected to suit the application.
The ADXL103 and ADXL203 are available in 5 mm × 5 mm × 2 mm, 8-pad hermetic LCC packages.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The ADXL203EB is a simple breakout board that allows quick evaluation of the performance of the ADXL203 accelerometer. The ADXL203 is a 2-axis, low-noise, temperature-stable accelerometer. The small size (1" x 1") of the ADXL203 makes it easy to mount the accelerometer to an existing system without the need for additional hardware and with minimal effect on performance of the system and of the accelerometer.
This page contains all the information related to the ADXL203EB including documentation, pricing, and ordering information.
