ADXRS453 MECHANICAL PERFORMANCE The ADXRS453 has excellent shock and vibration rejection. Figure 20 shows the output noise response of the ADXRS453 in a vibration free environment. Figure 21 shows the response of the same device rms random ...
Page 11
NOISE PERFORMANCE The ADXRS453 noise performance is very consistent from device to device and varies very predictably with temperature. Table 6 contains statistical noise data at three temperature points for a large population of ADXRS453 devices (more than 3000 parts ...

ADXRS453 APPLICATIONS INFORMATION CALIBRATED PERFORMANCE The ADXRS453 gyroscope uses internal EEPROM memory to store its temperature calibration information. The calibration information is encoded into the device during factory test. The calibration data is used to perform offset, gain, and self-test ...

ADXRS453 FAULT REGISTER BIT DEFINITIONS Table 14 describes the bits available for signaling faults to the user. The individual bits of the fault registers are updated asynchronously, depending on their respective detection criteria; however recommended that the fault ...
Page 19
PWR Bit The device performs a continuous check of the internal 3 V regulated voltage level. If either an overvoltage (OV) or under- voltage (UV) fault is asserted, the PWR bit is also asserted. This condition occurs if the regulated ...
