The ADIS16227 iSensor® is a complete vibration sensing system that combines wide bandwidth， triaxial acceleration sensing with advanced time domain and frequency domain signal processing. Time domain signal processing includes a programmable decimation filter and selectable windowing function. Frequency domain processing includes a 512 point， real-valued FFT for each axis， along with FFT averaging， which reduces the noise floor variation for finer resolution. The 16-record FFT storage system offers users the ability to track changes over time and to capture FFTs with multiple decimation filter settings. The 22 kHz sensor resonance and 100.2 kSPS sample rate provide a frequency response that is suitable for machine-health applications. The aluminum core provides excellent mechanical coupling to the MEMS acceleration sensors. An internal clock drives the data sampling and signal processing system during all operations， which eliminates the need for an external clock source. The data capture function has three modes that offer several options to meet the needs of many different applications. The SPI and data buffer structure provide convenient access to wide bandwidth sensor data. The ADIS16227 also offers a digital temperature sensor and digital power supply measurements. The ADIS16227 is available in a 15 mm × 15 mm × 15 mm module with a threaded hole for stud mounting with a 10-32 UNF screw. The dual-row， 1 mm， 14-pin， flexible connector enables simple user interface and installation. The ADIS16227 is footprint and pin-for-pin compatible with the ADIS16223. It has an extended operating temperature range of −40°C to +125°C.
