The ADIS16223 is a digital tri-axial vibration sensor from Analog Devices, with a ±70 g measurement range and 14 kHz bandwidth. It also features programmable digital filters, a data capture function, and capture modes for managing machine life.
The ADIS16223 iSensor® combines a tri‑axial MEMS accelerometer, on‑chip signal processing and a SPI‑compatible serial interface. It provides up to ±70 g measurement range, 14 kHz bandwidth, programmable digital filters and a 1024‑sample capture buffer for each axis.
The device operates from a single 3.15 V to 3.6 V supply, works from –40 °C to +125 °C, and delivers up to 72.9 kSPS sample rate. It includes built‑in temperature and power‑supply monitoring, alarm thresholds, and flash‑backed configuration registers for reliable long‑term machine‑health monitoring.
