MAX668EUB

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.

Possible equivalents from other vendors (digital temp sensors with I2C/SPI):
- TI: TMP102, TMP75, TMP103
- Analog Devices: ADT7420, ADT75
- Microchip: MCP9808
- NXP/Philips: LM75A, LM75B
If a 1‑wire interface is acceptable: Dallas/Maxim DS18B20.

Pin count: 8 pins (SO-8/DIP-8 package).
Function: Temperature sensor/monitor IC; provides an analog output (voltage proportional to temperature) and may include an over-temperature/threshold alert option.

MAX668EUB is manufactured by Maxim Integrated (Maxim Integrated Products, Inc.). Maxim Integrated is a semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits (it is now part of Analog Devices).

MAX668EUB is a temperature sensor/monitor used for temperature reading and thermal protection. Typical applications include:
- Computers/servers and telecom gear for CPU/GPU sensing and fan/thermal management
- Power supplies, motor drives, inverters, and other high-power electronics for over-temperature protection
- Automotive and battery-management systems for packs, inverters, and engine electronics monitoring
- Industrial equipment, PLCs, and instrumentation requiring temperature monitoring
- Consumer electronics and appliances (HVAC, climate control, smart devices)
- Medical devices and lab instrumentation needing accurate ambient/component temperature sensing

MAX668EUB comes in an 8-pin small-outline package (µSOP-8 / SOIC-8).
