Digital Tri-Axial Vibration Sensor
ADIS16223
GENERAL DESCRIPTION
The ADIS16223
iSensor®
is a tri-axial, digital vibration sensor
system that combines industry-leading
iMEMS®
sensing technology
with signal processing, data capture, and a convenient serial
peripheral interface (SPI). The SPI and data buffer structure
provide convenient access to wide bandwidth sensor data. The
22 kHz sensor resonance and 72.9 kSPS sample rate provide a
frequency response that is suitable for machine-health applications.
The programmable digital filter offers low-pass and band-pass
configuration options.
An internal clock drives the data sampling system during a data
capture event, which eliminates the need for an external clock
source. The data capture function has four different modes that
offer several capture trigger options to meet the needs of many
different applications.
The ADIS16223 also offers a digital temperature sensor, digital
power supply measurements, and peak output capture.

Retention lifetime equivalent at junction temperature (T
J
) = 85°C as per JEDEC Standard 22, Method A117. Retention lifetime decreases with junction temperature. See
Figure 15.
