Product Description
The KX220-1071 is a Tri-axis, silicon micromachined
accelerometer with a full-scale output range of ±20g (196 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 0.9 mm Land Grid Array (LGA) plastic package operating from
a 1.8V – 3.6V DC supply. The KX220 features an internal low pass filter that can be disabled or factory
programmed to 50Hz, 100Hz, 500Hz, 1kHz, or 2kHz.
There are 2 factory programmable modes of operation for the KX220:
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 KX220-1071 is factory programmed to be in MODE 00 with no low pass filter
