Product Overview

The LM95233CISD/NOPB is a precision temperature sensor from Texas Instruments, designed to provide comprehensive temperature monitoring for a variety of applications. This advanced integrated circuit is capable of measuring both its own temperature and the temperature of a remote diode-connected transistor, which can be used to accurately monitor the temperature of a CPU, GPU, or other high-performance ICs.

Key Features

• Dual Temperature Sensing: The LM95233CISD/NOPB is equipped with one local and three remote temperature sensors. The remote sensors are designed to be highly accurate when used with a 2N3904 transistor or similar device, allowing for precise temperature monitoring of external components.
• High Accuracy: This sensor boasts an impressive ±1°C accuracy for both local and remote temperature readings, ensuring reliable and precise temperature data.
• Interface: Communication with the LM95233CISD/NOPB is simplified through an industry-standard 2-wire SMBus serial interface, which is compatible with I²C.
• Programmable Resolution: The ADC resolution for the remote channel is programmable from 8 to 11 bits, while the local channel has a fixed 9-bit resolution. This provides flexibility in balancing the trade-off between resolution and conversion time.
• TruTherm™ Technology: Texas Instruments' proprietary TruTherm technology enables the sensor to handle modern, high-performance ICs with thermal diode outputs that can be non-linear, ensuring accurate temperature readings.
