Monolithic Accelerometer

With Signal Conditioning

ADXL50*

For convenience, the ADXL50 has an internal buffer amplifier

with a full 0.25 V to 4.75 V output range. T his may be used to

set the zero-g level and change the output sensitivity by using

external resistors. External capacitors may be added to the resis-

tor network to provide 1 or 2 poles of filtering. No external

active components are required to interface directly to most

analog-to-digital converters (ADCs) or microcontrollers.

FEATURES

Com plete Acceleration Measurem ent System

on a Single Monolithic IC

Full-Scale Measurem ent Range: ؎50 g

Self-Test on Digital Com m and

+5 V Single Supply Operation

Sensitivity Precalibrated to 19 m V/ g

Internal Buffer Am plifier for User Adjustable Sensitivity

and Zero-g Level

Frequency Response: DC to 10 kHz

Post Filtering w ith External Passive Com ponents

High Shock Survival: >2000 g Unpow ered

Other Versions Available: ADXL05 (؎5 g)

T he ADXL50 uses a capacitive measurement method. T he ana-

log output voltage is directly proportional to acceleration, and is

fully scaled, referenced and temperature compensated, resulting

in high accuracy and linearity over a wide temperature range.

Internal circuitry implements a forced-balance control loop that

improves accuracy by compensating for any mechanical sensor

variations.

GENERAL D ESCRIP TIO N

T he ADXL50 is powered from a standard +5 V supply and is

robust for use in harsh industrial and automotive environments

and will survive shocks of more than 2000 g unpowered.

T he ADXL50 is a complete acceleration measurement system on

a single monolithic IC. T hree external capacitors and a +5 volt

power supply are all that is required to measure accelerations up

to ±50 g. Device sensitivity is factory trimmed to 19 mV/g,

resulting in a full-scale output swing of ±0.95 volts for a ±50 g

applied acceleration. Its zero g output level is +1.8 volts.

T he ADXL50 is available in a hermetic 10-pin T O-100 metal

can, specified over the 0°C to +70°C commercial, and –40°C to

+85°C industrial temperature ranges. Contact factory for avail-

ability of devices specified for operation over the –40°C to

+105°C automotive temperature range.

A T T L compatible self-test function can electrostatically deflect

the sensor beam at any time to verify device functionality.
