APPLICATIONS INFORMATION
INSTALLATION/HANDLING
INTERFACE PRINTED CIRCUIT BOARD (PCB)
For ADIS16367 installation, use the following two-step process:
The ADIS16367/PCBZ includes one ADIS16367BLMZ and
1. Secure the baseplate using machine screws.
2. Press the connector into its mate.
one interface PCB. The interface PCB simplifies the process
of integrating the ADIS16367BMLZ into an existing processor
system.
For removal,
J1 and J2 are dual-row, 2 mm (pitch) connectors that work with
1. Gently pry the connector from its mate using a small slot
a number of ribbon cable systems, including 3M Part Number
screwdriver.
152212-0100-GB (ribbon crimp connector) and 3M Part Number
2. Remove the screws and lift the part up.
3625/12 (ribbon cable). Figure 17 provides a hole pattern design
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.
E The AN-1041 Application Note, iSensor® IMU Quick Start
Guide and Bias Optimization Tips, provides more information
about developing an appropriate mechanical interface design.
T 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.
E The precision autonull command (GLOB_CMD[4]) provides
a simple predeployment method for correcting these errors to
an accuracy of approximately 0.013°/sec, using an average of
L 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.
O Refer to the AN-1041 Application Note for more information
about optimizing performance.
INPUT ADC CHANNEL
S 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
B 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.
OVCC
for installing the ADIS16367BMLZ 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 ADIS16367 does not require external capacitors for normal
operation; therefore, the interface PCB does not use the C1/C2
pads (not shown in Figure 17).
