The LM95231CIMMX/NOPB is a high-precision dual remote diode temperature sensor designed by Texas Instruments, which is renowned for its advanced monitoring capabilities. This precision sensor is specifically engineered to accurately measure the temperature of two remote diode-connected transistors, as well as its own die temperature. It is a popular choice for various applications, including desktop and notebook computers, industrial and medical equipment, and embedded systems.

The LM95231CIMMX/NOPB is capable of sensing temperature with a resolution of 0.125°C and an accuracy of ±1°C for external diode temperatures ranging from -40°C to +125°C, and ±3°C for temperatures up to +150°C. Its local temperature accuracy is ±3°C within the same temperature range. This high degree of precision makes it an ideal component for systems that require reliable temperature monitoring to maintain optimal performance and safety.

This sensor communicates over a 2-wire SMBus 2.0-compatible bus, which allows for easy integration into existing systems. It also features a TruTherm™ technology that supports the use of 3904 NPN or PNP transistors, providing greater flexibility in choosing the appropriate external temperature sensors for your application.

The LM95231CIMMX/NOPB comes in a small 10-pin VSSOP package, making it suitable for space-constrained applications. It is also characterized for operation over a wide supply voltage range of 3.0V to 3.6V, which allows for versatility in different system designs. The device's low supply current minimizes the impact on overall system power consumption, making it an energy-efficient choice for portable and battery-powered applications.

The "NOPB" suffix indicates that this product is part of Texas Instruments' eco-friendly lineup, which means it is provided without lead (Pb) and is RoHS compliant. This commitment to environmental sustainability ensures that the LM95231CIMMX/NOPB meets current regulations and can be used in products sold worldwide.

Overall, the LM95231CIMMX/NOPB from Texas Instruments stands out for its precision, reliability, and versatility, making it a top-tier component for temperature monitoring in a wide range of electronic systems.
