Accelerometer Specifications  
KXTC9-2050  
Rev. 1  
Jun-2010  
Product Description  
The KXTC9-2050 is  
a
Tri-axis, silicon micromachined  
accelerometer with a full-scale output range of +/-2g (19.6 m/s/s).  
The sense element is fabricated using Kionix’s proprietary plasma  
micromachining process technology. Acceleration sensing is based  
on the principle of a differential capacitance arising from  
acceleration-induced motion of the sense element, which further  
utilizes common mode cancellation to decrease errors from  
process variation, temperature, and environmental stress. The  
sense element is hermetically sealed at the wafer level by bonding  
a second silicon lid wafer to the device using a glass frit. A  
separate ASIC device packaged with the sense element provides  
signal conditioning and self-test. The accelerometer is delivered in  
a 3 x 3 x 0.9mm Land Grid Array (LGA) plastic package operating  
from a 1.8 – 3.6V DC supply. The KXTC9 features a factory  
programmable low pass filter.  
There are 2 factory programmable modes of operation for the KXTC9:  
Mode 00 – The Enable pin must be high for normal operation and low for power shutdown.  
Mode 01 – The Enable pin must be low for normal operation and high for power shutdown.  
The KXTC9-2050 is factory programmed to be in MODE 00.

Application Design Equations  
The bandwidth is determined by a factory programmable switched capacitor filter. The filter can be set at  
the factory to be 2kHz, 1kHz, 500Hz, 100Hz, 50Hz, or no low pass filter. Alternatively, bandwidth can be  
reduced by addition of a capacitor on the output pins 5, 6, and 7 according to the equation:
