Annotated Snippet
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_en
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Dither enable. Write 1 to enable dither or 0 to disable it. This is useful
for changing the dither parameters. They way it should be done is:
- disable dither operation;
- change dither parameters (eg: frequency, phase...);
- enabled dither operation
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_raw
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
This raw, unscaled value refers to the dither signal amplitude.
The same scale as in out_voltageY_raw applies. However, the
offset might be different as it's always 0 for this attribute.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_raw_available
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Available range for dither raw amplitude values.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_offset
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Offset applied to out_voltageY_dither_raw. Read only attribute
always set to 0.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_frequency
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Sets the dither signal frequency. Units are in Hz.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_frequency_available
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Returns the available values for the dither frequency.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_phase
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Sets the dither signal phase. Units are in Radians.
What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_phase_available
KernelVersion: 5.18
Contact: linux-iio@vger.kernel.org
Description:
Returns the available values for the dither phase.Annotation

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
