GENERAL DESCRIPTION
The 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 2
g
. 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 0.5 ms to 10 ms via a single
resistor (R
SET
).

The typical noise floor is 200
2 m
g
(at 60 Hz bandwidth) to be resolved.
The bandwidth of the accelerometer is set with capacitors C
X
and
C
Y
at the X
FILT
and Y

pins. An analog output can be recon-
structed by filtering the duty cycle output.
The ADXL202E is available in 5 mm 5 mm 2 mm 8-lead
hermetic LCC package.
