Maxim Integrated MAX6640AEE Dual-Channel Temperature Sensor

The Maxim Integrated MAX6640AEE is a high-precision, dual-channel temperature sensor designed to monitor the temperature of both a remote thermal diode (typically located in a CPU, GPU, or other semiconductor die) and its own internal temperature. It is an ideal solution for complex systems where temperature monitoring and control are critical for performance and reliability.

Key Features

• Dual Temperature Sensing: The MAX6640AEE is capable of measuring the temperature of two sources: an external diode-connected transistor, such as a CPU or GPU, and its own internal sensor for ambient temperature monitoring.
• High Accuracy: It offers excellent accuracy for remote diode readings (±1°C) and local temperature measurements (±3°C).
• Programmable Overtemperature Alarms: Users can set overtemperature threshold alarms for both the remote and local sensors, ensuring proactive measures can be taken to prevent overheating.
• SMBus/I²C-Compatible Serial Interface: The device supports a serial interface for communication with a host controller, providing easy integration into system management buses.
• Wide Temperature Range: The MAX6640AEE operates over a wide temperature range, making it suitable for various environments and applications.
