FEATURES FUNCTIONAL BLOCK DIAGRAM Triaxis digital gyroscope with digital range scaling ±75°/sec, ±150°/sec, ±300°/sec settings Tight orthogonal alignment: 5.25 V (1 = power supply > 5.25 V, 0 = power supply ≤ 5.25 V) Power supply < 4.75 V (1 = power supply < 4.75 V, 0 = power supply ≥ 4.75 V) Alarm Registers The alarm function provides monitoring for two independent conditions. The ALM_CTRL register provides control inputs for data source, data filtering (prior to comparison), static comparison, dynamic rate-of-change comparison, and output indicator configurations. The ALM_MAGx registers establish the trigger threshold and polarity configurations. Table 30 gives an example of how to configure a static alarm. The ALM_SMPLx registers provide the numbers of samples to use in the dynamic rate-of-change configuration. The period equals the number in the ALM_SMPLx register multiplied by the sample period time, which is established by the SMPL_PRD register. See Table 31 for an example of how to configure the sensor for this type of function. Setting MSC_CTRL[11] = 1 (DIN = 0xB508) performs a checksum verification of the flash memory locations. The pass/fail result is loaded into DIAG_STAT[6]. Rev. F | Page 15 of 20 ADIS16362 Data Sheet Table 27. ALM_MAG1, ALM_MAG2 Bit Descriptions Table 30.

All four registers are two bytes in length. When using the SERIAL_NUM value to calculate the serial number, mask off the upper four bits and convert the remaining 12 bits to a decimal number.

Gently pry the connector from its mate using a small slot screwdriver. Remove the screws and lift the part up. Never attempt to unplug the connector by pulling on the plastic case or baseplate. Although the flexible connector is very reliable in normal operation, it can break when subjected to unreasonable handling. When broken, the flexible connector cannot be repaired. The AN-1041 Application Note provides more information about developing an appropriate mechanical interface design. Figure 16. Equivalent Analog Input Circuit (Conversion Phase: Switch Open, Track Phase: Switch Closed) ADIS16IMU2/PCBZ The ADIS16IMU2/PCBZ accessories provide a simplified method for connecting the ADIS16362 to an embedded processor platform or to the EVAL-ADIS2 evaluation system. Figure 17 provides the pin assignments for J1 on the ADIS16IMU2/PCBZ breakout board. J1 GYROSCOPE BIAS OPTIMIZATION The factory calibration addresses initial bias errors along with temperature-dependent bias behaviors. Installation and certain environmental conditions can introduce modest bias errors. The precision autonull command (GLOB_CMD[4]) provides a simple predeployment method for correcting these errors to an accuracy of approximately 0.008°/sec, using an average of 30 sec. Averaging the sensor output data for 100 sec can provide incremental performance gains, as well. Controlling device rotation, power supply, and temperature during these averaging times helps to ensure optimal accuracy during this process. Refer to the AN-1041 Application Note for more information about optimizing performance. D 08179-014 Secure the baseplate using machine screws. Press the connector into its mate.

J1 Pin Assignments for the ADIS16IMU2/PCBZ The C1 and C2 locations on the ADIS16IMU2/PCBZ provide users with the pads to install capacitance across VDD and GND, which Figure 9 recommends for best performance. PC-BASED EVALUATION TOOLS INPUT ADC CHANNEL The AUX_ADC register provides access to the auxiliary ADC input channel. The ADC is a 12-bit successive approximation converter that has an input circuit equivalent to the one shown in Figure 16. The maximum input is 3.3 V. The ESD protection diodes can handle 10 mA without causing irreversible damage. The on resistance (R1) of the switch has a typical value of 100 Ω. The sampling capacitor, C2, has a typical value of 16 pF. The EVAL-ADIS2 supports PC-based evaluation of the ADIS16362. Refer to the EVAL-ADIS2 Evaluation System Wiki Guide for more information on connecting the ADIS16362 to the EVAL-ADIS2 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 ADIS16362 to this type of inspection. Rev.
