Product Description
The KXTH5-4325 is a Tri-axis, silicon micromachined
accelerometer with a full-scale output range of +/-2.75g (27 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 5 x 0.9mm Land Grid Array (LGA) plastic package operating
from a 1.8 – 3.6 V DC supply. The KXTH5 features a factory
programmable low pass filter.
There are 2 factory programmable modes of operation for the KXTH5:
Mode 00
– The PD pin must be
high
for normal operation and
low
for power shutdown.
Mode 01
– The PD pin must be
low
for normal operation and
high
for power shutdown.
The KXTH5-4325 is factory programmed to be in MODE 01.

Notes:
1. Input High Voltage on Pin ST is 0.7 * V
dd.
2. Power up time is determined by 5 times the RC time constant of the factory programmed or
user defined low pass filter.
3. Mux Switching Time is defined as a transition from 10% to 90% with a 10pF load.
4. Factory programmable to have a switched capacitor low pass filter at 2kHz, 1kHz, 500Hz,
100Hz, 50Hz, or no low pass filter. Optionally, the user can define with external capacitors.
Maximum defined by the frequency response of the sensors.
