Description
MAX668EUB is a Maxim Integrated digital temperature sensor IC (part of the MAX668/669 family). It converts ambient or remote temperature to a digital code that a microcontroller reads over a serial data interface. The EUB suffix simply denotes a specific package variant.
Key points:
- Single-supply operation, small package, low power in normal use
- Digital output with a defined temperature-resolution and accuracy per the datasheet
- Used for onboard or remote temperature monitoring, thermal protection, and fan-control schemes in embedded systems
Typical applications include CPU/system temperature monitoring, datacom equipment, and HVAC/industrial controls. For exact performance (temperature range, accuracy, interface protocol, pinout, and power requirements), consult the MAX668EUB datasheet and packaging details.
