GENERAL DESCRIPTION
The ADXL210E is a low-cost, low-power, complete 2-axis acceler-
ometer with a digital output, all on a single monolithic IC. It is an
improved version of the ADXL210AQC/JQC. The ADXL210E
will measure accelerations with a full-scale range of ± 10 g. The
ADXL210E can measure both dynamic acceleration (e.g., vibra-
tion) and static acceleration (e.g., gravity).
The outputs are analog voltage or digital signals whose duty cycles
(ratio of pulsewidth to period) are proportional to acceleration.
The duty cycle outputs can be directly measured by a micro-
processor counter without an A/D converter or glue logic. The
duty cycle period is adjustable from 0.5 ms to 10 ms via a single
resistor (RSET).
The typical noise floor is 200 gHz, allowing signals below
2 mg (at 60 Hz bandwidth) to be resolved.
The bandwidth of the accelerometer is set with capacitors CX and
CY at the XFILT and YFILT pins. An analog output can be recon-
structed by filtering the duty cycle output.
The ADXL210E is available in a 5 mm ϫ 5 mm ϫ 2 mm 8-lead
hermetic LCC package.

1Guaranteed by measurement of initial offset and sensitivity.
2See Typical Performance Characteristics.
3Alignment error is specified as the angle between the true and indicated axis of sensitivity (see TPC 15).
4Cross-axis sensitivity is the algebraic sum of the alignment and the inherent sensitivity errors.
5Defined as the output change from ambient to maximum temperature or ambient to minimum temperature.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADXL210E features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
