CONFIGURATION OPTIONS
Synchronization Input
The SYNC pin can be used to synchronize the ADIS16130 with
other devices in the system. When the SYNC bit in the I/O port
register (IOP) is set and the SYNC pin is low, the ADIS16130
does not process any conversions. Instead, it waits until the
SYNC pin goes high, and then starts the operation. This allows
the conversion to start from a known point in time (for example,
the rising edge of the SYNC pin).
Self-Test Function
The self-test function enables system-level diagnostic checks for the
entire ADIS16130 sensor/signal conditioning circuit. To activate
the self-test function, there must be a logic high signal on all
ST pins (see Table 5). When activated, the self-test function results
in a rate measurement shift. By comparing the observed shift
with the limits specified in this data sheet, users can determine
the pass/fail criteria for system-level diagnostic routines.For
normal gyroscope operation, place a logic low input on
all ST pins. For systems that do not require this feature, tie all
ST pins to GND.
Analog Bandwidth
The typical −3 dB cutoff frequency for the ADIS16130 is
300 Hz, which is the combined response of two single-pole
filters, as shown in Figure 14. Pin ROA1 and Pin ROA2 provide
