The mounting and installation process can influence gyroscope bias repeatability and other key parametric behaviors. To preserve the best performance, use the following guidelines when developing an attachment approach for the ADIS16445: • • Focus mounting force at the machine screw locations. Avoid direct force application on the substrate. Avoid placing mounting pressure on the package lid, except for the edges that border the exposed side of the substrate. Use a consistent mounting torque of 28 inch-ounces on mounting hardware. Avoid placing translational forces on the electrical connector. 1 2 SCLK CS 3 4 DOUT DNC 5 6 DIN GND 7 8 GND GND 9 10 VDD VDD 11 12 VDD DIO1 13 14 DIO2 DIO3 15 16 DIO4/CLKIN 11051-023 • • • J1 RST Figure 22.

The C1 and C2 locations on the ADIS16IMU2/PCBZ provide users with the pads to install 10 µF of capacitance across VDD and GND, which Figure 9 recommends for best performance. POWER SUPPLY CONSIDERATIONS PC-BASED EVALUATION TOOLS The power supply must be within 3.15 V and 3.45 V for normal operation and optimal performance. During start up, the internal power conversion system starts drawing current when VDD reaches 1.6 V. The internal processor begins initializing when VDD is equal to 2.35 V. After the processor starts, VDD must reach 2.7 V within 128 ms. Also, make sure that the power supply drops below 1.6 V to shut the device down. Figure 9 shows a 10 µF capacitor on the power supply. Using this capacitor supports optimal noise performance in the sensors. The EVAL-ADIS2 supports PC-based evaluation of the ADIS16445. Please refer to the EVAL-ADIS2 Evaluation System Wiki Guide for more information on connecting the ADIS16445 to the EVAL-ADIS2 evaluation system. X-RAY SENSITIVITY Exposure to high dose rate X-rays, such as those in production systems that inspect solder joints in electronic assemblies, may affect accelerometer bias errors. For optimal performance, avoid exposing the ADIS16445 to this type of inspection. ADIS16IMU2/PCBZ The ADIS1644X/FLEX and ADIS16IMU2/PCBZ accessories provide a simple method for connecting to an embedded processor platform or to the EVAL-ADIS2 evaluation system. Figure 23 provides a mechanical design example for using these two components with the ADIS16445 IMU in a system. 15mm TO 45mm 23.75mm 33.40mm J2 2 1 16 J1 15 15.05mm 20.15mm 10.07mm 24 23 2 1 30.10mm ADIS16IMU2/PCBZ (INTERFACE BOARD) NOTES 1.
