ADXL203:  Precision ±1.7 g, ±5 g, ±18 g Dual-Axis iMEMS® Accelerometer

Product Details


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.

Applications
  • Vehicle dynamic control (VDC)/electronic stability program (ESP) systems
  • Electronic chassis control
  • Electronic braking

In this reference circuit, the output voltage of the ADXL203 dual axis accelerometer, produced by acceleration in the x- or y-axis, passes through buffers to attenuate and level shift the sensor outputs so they are at proper levels for conversion.
