Overview
a FEATURES Complete Acceleration Measurement System on a Single Monolithic IC Full-Scale Measurement Range: ؎ 50 g Self-Test on Digital Command +5 V Single Supply Operation Sensitivity Precalibrated to 19 mV/g Internal Buffer Amplifier for User Adjustable Sensitivity and Zero-g Level Frequency Response: DC to 10 kHz Post Filtering with External Passive Components High Shock Survival: >2000 g Unpowered Other Versions Available: ADXL05 (؎5 g) GENERAL DESCRIPTION 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.
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 resistor 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 analog 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 availability of devices specified for operation over the –40°C to +105°C automotive temperature range.
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.
