The ADXL204 is a high precision, single-/dual-axis MEMS® accelerometer with ±1.7 g resolution, low power consumption, and is suitable for applications such as vehicle dynamic control (VDC)/electronic stability program (ESP) systems, electronic chassis controls, electronic braking, platform stabilization/leveling, navigation, alarms and motion detectors.
The ADXL204 is a dual‑axis iMEMS accelerometer on a single IC chip, specified for 3.3 V operation but functional from 3 V to 6 V. It offers high zero‑g bias stability, low power consumption (500 pA typical), and a shock rating of 3500 g. Bandwidth can be set from 0.5 Hz to 2.5 kHz using external capacitors Cx and Cy, making it suitable for vibration, tilt sensing, and vehicle dynamics applications.
The datasheet provides full electrical specifications, pin configuration, typical performance curves, and guidelines for using the device as a dual‑axis tilt sensor. Ordering information and package dimensions for the 8‑terminal LCC package are also included.
