The LM75AIMME/NOPB is a digital local temperature sensor from Texas Instruments, part of the LM75 family. It outputs a 9-bit digital value over an I²C bus, with a programmable limit and an open-drain output switch that can trigger an interrupt or fan control when the temperature crosses a threshold.
Accuracy and temperature range — what the ratings mean for your BOM
That ±2°C is tight enough for thermal management — think monitoring a processor heatsink or a power-supply ambient — but not for precision calibration or medical thermometry. The 9-bit resolution gives 0.5°C per LSB, which is adequate for most system-monitoring tasks. The supply voltage spans 2.7V to 5.5V, so it can run off a 3.3V or 5V rail without a separate regulator.
