LM95231EVAL [Texas Instruments]

The LM95231 is a precision dual remote diode temperature sensor (RDTS) that uses TruTherm technology to accurately measure temperatures of remote ICs or diode junctions. It senses three temperature zones: its own die and two diode-connected transistors. Features include digital and analog filtering, programmable resolution for remote (10/11-bit or 12/13-bit) and local (9-bit) readings, remote diode fault detection, programmable conversion rate, shutdown mode, and SMBus 2.0 compatible interface with TIMEOUT support. Key specifications include remote temperature accuracy of ±0.75°C max, local accuracy of ±3.0°C max, supply voltage 3.0V-3.6V, and typical supply current of 402µA.
