The operating temperature range of -40°C to +125°C covers industrial and extended-temperature environments — suitable for outdoor base stations, motor drives, or engine-bay electronics where the ambient can swing well beyond commercial limits. ## Lifecycle and sourcing The MAX6639FAEE+ carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so the part is safe to specify for new production runs. Sourcing is through independent distribution; submit an RFQ for current pricing and availability.","metaTitle":"MAX6639FAEE+ Temp Monitor, ±1°C Remote Accuracy, 16-QSOP","metaDescription":"MAX6639FAEE+ temperature monitor from Analog Devices. ±1°C remote accuracy, I²C/SMBus interface, integrated fan control.
