Secure the baseplate using machine screws. Press the connector into its mate. C1 VCC D R1 C2 08179-014 D For removal, 1. 2. Gently pry the connector from its mate using a small slot screwdriver. Remove the screws and lift the part up. Figure 15. Equivalent Analog Input Circuit (Conversion Phase: Switch Open, Track Phase: Switch Closed) INTERFACE PRINTED CIRCUIT BOARD (PCB) The ADIS16362/PCBZ includes one ADIS16362BLMZ and one interface PCB. The interface PCB simplifies the process of integrating the ADIS16362BMLZ 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 16 provides a hole pattern design for installing the ADIS16362BMLZ and the interface PCB onto the same surface. Figure 17 provides the pin assignments for each connector. The pin descriptions match those listed in Table 5. The ADIS16362 does not require external capacitors for normal operation, so the interface PCB does not use the C1/C2 pads (not shown in Figure 16). 23.75 21.24 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. 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. J2 1 2 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 15. 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. 11 12 30.10 J1 1 2 27.70 1.20 11 12 08179-020 NOTES 1. DIMENSIONS IN MILLIMETERS. Figure 16.
