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.

Output of the internal 3.4 V voltage reference.

ST

The digital self-test input. It is both CMOS and TTL

compatible.

The ADXL50 preamplifier output providing an output

voltage of 19 mV per g of acceleration.

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.
