Product details

System temperature monitor with SMBus interface

The Analog Devices ADM1020AR-REEL7 is a system temperature monitor that combines an internal temperature sensor with support for an external diode-connected transistor, reporting readings over an SMBus interface. It delivers ±1°C accuracy across the full -55°C to 125°C operating range, making it suitable for thermal management in avionics, satellite payloads, downhole instrumentation, and other high-reliability environments where the board must survive extreme cold and heat.

Package and mounting

Housed in an 8-SOIC (0.154", 3.90 mm width) surface-mount package. The 8-pin SOIC footprint is a standard layout shared by many temperature sensors and EEPROMs, so board layout is straightforward.

Lifecycle and sourcing

Marked Active in the lifecycle record — no last-time-buy or obsolescence risk for new designs. RoHS non-compliant per the listing, so verify your assembly-house restrictions if you need lead-free solder.

Frequently asked questions

What is the accuracy of ADM1020AR-REEL7?

The ADM1020AR-REEL7 specifies ±1°C accuracy. This applies across the full -55°C to 125°C operating range for the internal sensor; the external diode channel accuracy depends on the diode ideality factor and layout parasitics.

Does ADM1020AR-REEL7 work with a 3.3V supply?

Yes, the supply range is 3V to 5.5V, so a 3.3V rail is well within spec. The SMBus interface levels follow the supply voltage.

What is the difference between ADM1020AR and ADM1020AR-REEL7?

The ADM1020AR-REEL7 is the same die as the ADM1020AR but shipped in Bulk packaging (the -REEL7 suffix indicates a reel quantity variant). Functionally identical — same ±1°C accuracy, same SMBus interface, same internal/external sensor topology.
