ADIS16364 Data Sheet
FEATURES GENERAL DESCRIPTION Triaxis digital gyroscope with digital range scaling
±75°/sec, ±150°/sec, ±300°/sec settings
Tight orthogonal alignment: 5.25 V
1 = power supply > 5.25 V, 0 = power supply ≤ 5.25 V
Power supply < 4.75 V
1 = power supply < 4.75 V, 0 = power supply ≥ 4.75 V ADIS16364 Data Sheet Alarm Registers
The alarm function provides monitoring for two independent
conditions. The ALM_CTRL register provides control inputs
for data source, data filtering (prior to comparison), static
comparison, dynamic rate-of-change comparison, and output
indicator configurations. The ALM_MAGx registers establish
the trigger threshold and polarity configurations. Table 30 gives
an example of how to configure a static alarm. The ALM_SMPLx
registers provide the number of samples to use in the dynamic
rate-of-change configuration. The period equals the number in
the ALM_SMPLx register multiplied by the sample period time,
which is established by the SMPL_PRD register. See Table 31 for
an example of how to configure the sensor for this type of function.

ADIS16364 Silicon Anomaly
ADIS16364 ANOMALIES This anomaly list describes the known bugs, anomalies, and workarounds for the ADIS16364.
Analog Devices, Inc., is committed, through future silicon revisions, to continuously improve silicon functionality. Analog Devices tries
to ensure that these future silicon revisions remain compatible with your present software/systems by implementing the recommended
workarounds outlined here. ANOMALY STATUS
Reference Number
er001 Description
MSC_CTRL register programmed with incorrect default value Status
Fixed MSC_CTRL DEFAULT VALUE INCORRECT [er001]
Background
Issue Workaround Related Issues The ADIS16365 offers a data ready option with either DIO1 or DIO2, depending on the setting in MSC_CTRL Bits[2:0].
The factory default setting for MSC_CTRL is 0x0006, which sets DIO1 as a positive pulse, data ready signal. For some parts
with a date code earlier than 0918, the factory default value was 0x0000, which disables the data ready function on DIO1.
This has been resolved, and all new parts have a factory default setting of 0x0006 for MSC_CTRL. In addition, after this
error was discovered, all existing inventory was corrected.
When the power supply reaches 4.75 V, wait 500 ms to ensure that the part has started up, and then set MSC_CTRL Bits[7:0] =
0x06 by writing DIN = 0xB406. Next, execute a manual flash update by writing DIN = 0xBE08 (GLOB_CMD Bit3 = 1). Wait 100 ms,
and then the device will operate with DIO1 as a positive pulse, data ready signal, and the setting will be nonvolatile.
