The ADXL213 is a low cost, low power, complete dual axis accelerometer with signal conditioned, duty cycle modulated outputs, all on a single monolithic IC. The ADXL213 measures acceleration with a full-scale range of ±1.2 g (typical).
The ADXL213 is a low‑cost, low‑power dual‑axis accelerometer offered in an 8‑lead CLCC package. It provides pulse‑width‑modulated digital outputs whose duty cycle is proportional to acceleration, allowing direct measurement without an A/D converter.
The handbook includes full specifications, absolute maximum ratings, typical performance data, theory of operation, pin descriptions, mechanical dimensions, ESD precautions, and ordering information, helping designers integrate the device into automotive, navigation, and motion‑detection applications.

The device measures acceleration up to +1.2 g.
The typical noise density is 160 µg/V·Hz rms at 25 °C.
It operates from 3 V to 6 V.
Bandwidth is selected by adding external capacitors Cx and Cy as described by the formula Bandwidth = 1/(2 × 7 × 32 kΩ × C).
