The ADIS16495 and ADIS16497 are inertial systems that include a triaxis gyroscope and a triaxis accelerometer. The serial peripheral interface (SPI) provide a simple interface for data collection and configuration control. The devices are similar to ADIS16475, ADIS16480, ADIS16485 and ADIS16488, the main differences are highlighted below: * The temperature data scale is 0.00565 C/LSB for ADIS16475 and ADIS1648x devices, while for ADIS1649x 0.0125 C/LSB. * ADIS1649x devices support different gyroscope measurement ranges which are dependent on the dash number (-1, -2, -3), see Table 24 in the ADIS16495 datasheet. However, the ADIS16497 gyroscopes have the same scale as ADIS16495. * ADIS16495 devices support the acceleration maximum range of 8g, while ADIS16497 devices go up to 40g. * The internal clock for ADIS1649x devices is 4.25 kSPS. The sampling frequency is calculated by applying a decimation rate which can take a maximum value of 4250. * ADIS1649x devices support different default filter frequencies.
