APPLICATIONS INFORMATION
INSTALLATION/HANDLING
For ADIS16364 installation, use the following two-step process:
1.
2.
For removal,
1.
2.
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
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 incre-
mental 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.
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.
AN-1041
Secure the baseplate using machine screws.
Press the connector into its mate.
Gently pry the connector from its mate using a small slot
screwdriver.
Remove the screws and lift the part up.

INTERFACE PRINTED CIRCUIT BOARD (PCB)
The ADIS16364/PCBZ includes one ADIS16364BMLZ and one
interface PCB. The interface PCB simplifies the process of inte-
grating the ADIS16364BMLZ into an existing processor system.
J1 and J2 are dual-row, 2 mm (pitch) connectors that work
with a number of ribbon cable systems, including 3M Part
Number 152212-0100-GB (ribbon crimp connector) and
3M Part Number 3625/12 (ribbon cable). Figure 17 provides
a hole pattern design for installing the ADIS16364BMLZ and
the interface PCB onto the same surface. Figure 18 provides the
pin assignments for each connector. The pin descriptions match
those listed in Table 5. The ADIS16364 does not require external
capacitors for normal operation; therefore, the interface PCB
does not use the C1/C2 pads (not shown in Figure 17).
