Low Cost ±1.2g Dual Axis Accelerometer
The ADXL213 is a low cost, low power, complete dual axis accelerometer with signal conditioned, duty cycle modulated outputs, all on a single monolithic IC. The ADXL213 measures acceleration with a full-scale range of ±1.2 g (typical). The ADXL213 can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity).
The outputs are digital signals whose duty cycles (ratio of pulse width to period) are proportional to acceleration (30%/g). The duty cycle outputs can be directly measured by a microcontroller without an A/D converter or glue logic.
Innovative design techniques are used to ensure high zero g bias stability (typically better than 0.25 mg/°C), as well as tight sensitivity stability (typically better than 50 ppm/°C).
The typical noise floor is 160 μg/√, allowing signals below 1 mg (0.06° of inclination) to be resolved in tilt sensing applications using narrow bandwidths (<60 Hz).
The user selects the bandwidth of the accelerometer using capacitors CX and CYM at the XFILT and YFILT pins. Bandwidths of 0.5 Hz to 250 Hz may be selected to suit the application.
The ADXL213 is available in a 5mm x 5mm x 2mm, 8-pad hermetic LCC package.Applications
This designates products ADI does not recommend broadly for new designs.
The ADXL213EBis a simple breakout board that allows quick evaluation of the performance of the ADXL213 accelerometer. The ADXL213 is a 2-axis, low-noise, temperature-stable accelerometer with PWM output. The small size (1" x 1") of the ADXL213EB makes it easy to mount the accelerometer to an existing system without the need for additional hardware and with minimal effect on performance of the system and of the accelerometer.
