Analog Devices ADT7316/7/8 and ADT7516/7/9 mixed-signal temperature/ADC/DAC chips
A family of small mixed-signal chips from Analog Devices that combine a digital temperature sensor, a few analog-to-digital input channels, and a handful of digital-to-analog outputs on a single I2C or SPI part. They are used on industrial and embedded boards where a designer wants basic environmental monitoring and a couple of analog control voltages without adding several separate chips.
recommendation
Worth keeping but documenting as a niche legacy part, because Analog Devices still lists the ADT7316 and ADT7516 as in-production chips in 2025 and the kernel code is still receiving upstream attention — Jonathan Cameron applied a power-management fix in January 2026 and a cleanup series followed in March 2026. Linux deployment is likely small, and the driver has lingered in the staging tree for years, so it makes sense to flag it as low-traffic rather than push it toward removal.

Analog Devices lists ADT7516 as PRODUCTION with pricing and an evaluation board, reinforcing that the family still has live production parts.
codex reasoning notes (technical)
Local exec_command inspection identified this as the ADT7316/7/8 + ADT7516/7/9 staging IIO driver; local git log showed substantive touches through 2026-01-11. All cited URLs were obtained via web search. The mailing-list hits show active maintenance/cleanup and no visible removal thread; the vendor pages show some family members remain in production, but these are niche mixed-signal sensor/ADC/DAC parts with likely low modern Linux deployment. Result: keep the driver, but annotate as legacy/staging and niche rather than deprecate/remove.
