Analogue, Mixed Signal, LSI
Analog Devices’ ADIS16227 iSensor is a tri-axial, digital vibration monitor that combines an industry-leading iMEMS sensor, data conversion and sensor processing technologies with convenient data capture and a serial peripheral interface (SPI). The SPI and data buffer structure provide access to wide-bandwidth sensor data. The 22 kHz sensor resonance and 100 kSPS sample rate provide a frequency response that is suitable for wide-bandwidth vibration monitoring applications. The ADIS16227 samples, processes and stores x, y and z acceleration data into the FFT (fast Fourier transform) buffer and FFT records (if selected), including time stamp. The programmable digital filter offers low-pass configuration options and an internal clock drives the data sampling system during a data capture event, which eliminates the need for an external clock source.
