Product details

What the ADM1027ARQ does on the board

Temperature accuracy is rated at ±1°C, which is tight enough for most system-level thermal management — server chassis, telecom line cards, or industrial control enclosures where a few degrees of headroom matter for fan noise vs. airflow balance.

Lifecycle and sourcing posture

The ADM1027ARQ is listed as Active in the lifecycle record — no end-of-life notification, no last-time-buy window. That means it remains a valid choice for new designs and ongoing production without forced requalification.

Frequently asked questions

Is ADM1027ARQ compatible with SMBus?

Yes, the output type is SMBus. The part communicates over the System Management Bus, which is standard for server and telecom thermal management interfaces.

Is ADM1027ARQ equivalent to ADT7460?

The ADM1027ARQ and the ADT7460 are both remote thermal controllers with fan control and ±1°C accuracy, but they are from different manufacturers (ON Semiconductor vs. Analog Devices). Pin compatibility and register maps differ — verify the datasheet for your specific firmware before substituting.
