GENERAL DESCRIPTION
The ADXL202/ADXL210 are low cost, low power, complete
2-axis accelerometers with a measurement range of either
±
2
g/
±
10
g
. The ADXL202/ADXL210 can measure both dy-
namic acceleration (e.g., vibration) and static acceleration (e.g.,
gravity).
The outputs are digital signals whose duty cycles (ratio of pulse-
width to period) are proportional to the acceleration in each of
the 2 sensitive axes. These outputs may be measured directly
with a microprocessor counter, requiring no A/D converter or
glue logic. The output period is adjustable from 0.5 ms to 10 ms
via a single resistor (R
SET
). If a voltage output is desired, a
voltage output proportional to acceleration is available from the
X
FILT
and Y
FILT
pins, or may be reconstructed by filtering the
duty cycle outputs.
The bandwidth of the ADXL202/ADXL210 may be set from
0.01 Hz to 5 kHz via capacitors C
X
and C
Y
. The typical noise
floor is 500
μ
g
/
√
Hz
allowing signals below 5 m
g
to be resolved
for bandwidths below 60 Hz.
The ADXL202/ADXL210 is available in a hermetic 14-lead
Surface Mount CERPAK, specified over the 0

C to +70
°
C
commercial or –40
°
C to +85
