Product Overview: LM75ADP from NXP

The LM75ADP is a precision integrated circuit temperature sensor with an I2C interface from the renowned semiconductor manufacturer, NXP Semiconductors. Designed for a wide range of applications, this digital temperature sensor provides a complete temperature monitoring system with a factory-calibrated accuracy of ±2°C from -25°C to +100°C and ±3°C over -55°C to +125°C.

Featuring a robust design, the LM75ADP operates over a supply voltage range of 2.8V to 5.5V, making it versatile for various electronic devices and systems. Its low power consumption and sleep mode make it ideal for power-sensitive applications.

Key Features

• Digital Accuracy: The sensor provides a digital output with a resolution of 0.125°C, allowing for precise temperature monitoring without the need for additional signal conditioning.
• Programmable Thresholds: Users can set both the overtemperature shutdown and hysteresis limits, enabling the sensor to act as a standalone thermostat without the need for constant polling by a host controller.
• Simple I2C Interface: The I2C bus facilitates easy integration into most microcontroller-based systems, supporting both standard and fast mode operations.
• Multiple Device Access: The LM75ADP supports a bus timeout feature that prevents bus lock-up, and with its three selectable address pins, up to eight devices can be connected to the same bus.

Applications

The LM75ADP is suitable for various applications, including:

• System thermal management
• Personal computers
• Electronics equipment
• Industrial controllers

With its compact form factor, the LM75ADP is available in small 8-pin packages such as SO8 and TSSOP8, ensuring a minimal footprint on the PCB. Its ease of use, combined with NXP's reputation for reliability, makes the LM75ADP a preferred choice for designers looking to incorporate temperature monitoring and control in their systems.
