Dynamic Range
The ADIS16354 provides three dynamic range settings: ±75°/s,
±150°/s, and ±300°/s. The lower dynamic range settings (75, 150)
limit the minimum filter tap sizes in order to maintain the resolu-
tion as the measurement range decreases. The recommended
order for programming the SENS/AVG register is upper byte
(sensitivity), followed by lower byte (filtering). The contents of
the SENS/AVG register are nonvolatile.

Auxiliary DAC
The auxiliary DAC provides a 12-bit level adjustment function.
The AUX_DAC register controls the operation of this feature. It
offers a rail-to-rail buffered output that has a range of 0 V to 2.5 V.
The DAC can drive its output to within 5 mV of the ground
reference when it is not sinking current. As the output
approaches ground, the linearity begins to degrade (100 LSB
beginning point). As the sink current increases, the nonlinear
range increases. The DAC output latch function, contained in
the COMMAND register, provides continuous operation while
writing each byte of this register. The contents of this register
are volatile, which means that the desired output level must be
set after every reset and power cycle event.

See the COMMAND register for use of the DAC latch
command, which enables the DAC to update its output based
on the value in the AUX-DAC register.
General-Purpose Input/Output
The ADIS16354 provides two general-purpose pins that enable
digital input/output control using the SPI. The GPIO_CTRL
control register establishes the configuration of these pins and
handles the SPI-to-pin controls. Each pin provides the flexibil-
ity of both input (read) and output (write) operations.
For example, writing 0x0202 to this register establishes Line 2 as
an output and sets its level as a 1. Writing 0x0000 to this register
establishes both lines as inputs, and their status can be read through
Bit 8 and Bit 9 of this register.
The digital input/output lines are also available for data-ready and
alarm/error indications. In the event of conflict, the following
priority structure governs the digital input/output configuration:
1.
