GENERAL DESCRIPTION

The

single- and dual-axis accelerometers with signal conditioned

voltage outputs, all on a single, monolithic IC. The ADXL103/

ADXL203

±5 g, or ±18 g. The

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 C

Bandwidths of 0.5 Hz to 2.5 kHz can be selected to suit the

application.

2 mm, 8-terminal ceramic LCC package.
