Digital local temp sensor with I²C interface
The LM75AIMX/NOPB is a digital local temperature sensor from Texas Instruments, communicating over an I²C bus with 9-bit resolution. It integrates an output switch with programmable limit, making it suitable for thermal monitoring and fan control in embedded systems.
Accuracy and supply flexibility
Accuracy is rated at ±2°C typical across the -25°C to 100°C range, widening to ±3°C at the extremes of -55°C to 125°C. The supply voltage range of 2.7V to 5.5V lets the sensor run from a 3.3V or 5V rail without a separate LDO, simplifying the power tree.
It is ROHS3 compliant, meeting current environmental requirements for new designs.
8-SOIC package for surface-mount assembly
Housed in an 8-SOIC package (0.154-inch width, 3.90 mm body), the LM75AIMX/NOPB is supplied on Tape & Reel or Cut Tape for pick-and-place.
