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
