GENERAL DESCRIPTIONThe ADXL202E 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 ADXL202AQC/JQC. The ADXL202E
will measure accelerations with a full-scale range of �2g. The
ADXL202E 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 0.5ms to 10ms via a single
resistor (RSET).
*Patents Pending
The typical noise floor is 200�g√Hz, allowing signals below
2mg (at 60Hz 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 ADXL202E is available in 5mm � 5mm � 2mm 8-lead
hermetic LCC package.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-

device at these or any other conditions above those indicate in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
Package Characteristics
ORDERING GUIDE
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADXL202E 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.
PIN FUNCTION DESCRIPTIONSDrops onto hard surfaces can cause shocks of greater than 1000g
and exceed the absolute maximum rating of the device. Care
should be exercised in handling to avoid damage.
