GENERAL DESCRIPTION
The ADXL50 is a complete acceleration measurement system on
a single monolithic IC. Three 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.
A TTL compatible self-test function can electrostatically deflect
the sensor beam at any time to verify device functionality.
For convenience, the ADXL50 has an internal buffer amplifier
with a full 0.25 V to 4.75 V output range. This 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.
The ADXL50 uses a capacitive measurement method. The 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.
The 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.
The ADXL50 is available in a hermetic 10-pin TO-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.
