*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only; the functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

PIN DESCRIPTION
+5 V
The power supply input pin.
C2
Connection for an external bypass capacitor (nominally
0.022
µF) used to prevent oscillator switching noise
from interfering with other ADXL50 circuitry. Please
see the section on component selection.
C1
Connections for the demodulator capacitor, nominally
0.022
µF. See the section on component selection for
application information.
COM The power supply common (or “ground”) connection.
VREF
Output of the internal 3.4 V voltage reference.
ST
The digital self-test input. It is both CMOS and TTL
compatible.
VPR
The ADXL50 preamplifier output providing an output
voltage of 19 mV per g of acceleration.
VOUT Output of the uncommitted buffer amplifier.
VIN–
The inverting input of the uncommitted buffer amplifier.

WARNING!
ESD SENSITIVE DEVICE
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 ADXL50 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.
