Product Description
The KXSS5-2057 is a Tri-axis, silicon micromachined accelerometer with a
full-scale output range of +/-3g (29.4 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, self-
test, and temperature compensation. The accelerometer is delivered in a 5
x 3 x 0.9 mm LGA plastic package operating from a 1.8 – 3.6V DC supply. The ASIC will trigger
interrupt signals if an acceleration threshold is exceeded in any axis (motion interrupt), or if the total
acceleration falls below a threshold (freefall interrupt). The thresholds can be set by the customer or
default to factory calibrated values. Either I²C or SPI interfaces can be used to communicate to the chip
to trigger A/D conversions, set thresholds or threshold delays, or manage power consumption.
