APPLICATIONS INFORMATION

INTERFACE PRINTED CIRCUIT BOARD (PCB)

The ADIS16305/PCBZ includes one ADIS16305ALMZ, one

interface PCB, and one interface flex. This combination simplifies

the process of prototype connections of the ADIS16305AMLZ

with 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 19 provides a hole pattern design

for installing the ADIS16305/PCBZ so that the flex fits well in

between the ADIS16305AMLZ and the interface PCB. Figure 20

provides the pin assignments for each connector, and the pin

descriptions match those listed in Table 5. The ADIS16305 does

not require external capacitors for normal operation; therefore,

the interface PCB does not use the C1/C2 pads (not shown in

Figure 19).

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 provides a simple predeployment

method for correcting these errors to an accuracy of approximately

0.008°/sec, using an average of 30 sec. Set GLOB_CMD[4] = 1

(DIN = BE10) to start this operation. 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.
