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 number 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.

PRODUCT IDENTIFICATION
Table 32 provides a summary of the registers that identify
the product: PROD_ID, which identifies the product type;
LOT_ID1 and LOT_ID2, the 32-bit lot identification code;
and SERIAL_NUM, which displays the 12-bit serial number.
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.

APPLICATIONS INFORMATION
INSTALLATION/HANDLING
ADIS16IMU2/PCBZ
For ADIS16364 installation, use the following two-step process:
The ADIS16IMU2/PCBZ accessories provide a simplified
method for connecting the ADIS16364 to an embedded
processor platform or to the EVAL-ADIS2 evaluation system.
Secure the baseplate using machine screws.
Press the connector into its mate.
Figure 17 provides the pin assignments for J1 on the
ADIS16IMU2/PCBZ breakout board.
For removal,
1.
2.
Gently pry the connector from its mate using a small slot
screwdriver.
Remove the screws and lift the part up.
J1
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, iSensor® IMU Quick Start Guide
and Bias Optimization Tips, provides more information about
developing an appropriate mechanical interface design.
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.

PC-BASED EVALUATION TOOLS
The EVAL-ADIS2 supports PC-based evaluation of the
ADIS16364. Refer to the EVAL-ADIS2 Evaluation System Wiki
Guide for more information on connecting the ADIS16364 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 ADIS16364 to this type of inspection.

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.
