Product details

Texas Instruments lists the LM75BIMX-5 as NRND (Not Recommended for New Designs). Existing production runs can still be sourced against an RFQ through independent distribution channels, but the part should not be dropped into a new board spin without a migration plan.

I²C digital temp sensor — bus integration

It reports temperature over a standard two-wire bus, making it straightforward to hang on a microcontroller's I²C port without an ADC channel.

Accuracy and features — what the numbers mean

Accuracy is ±2°C typical and ±3°C worst-case across the full temperature range. That ±3°C ceiling is the figure to budget for in a thermal-shutdown or fan-control loop — the system must tolerate that uncertainty at the extremes. Built-in features include a programmable temperature limit with an output switch (OS) that asserts when the measured temperature crosses the threshold, plus a shutdown mode that drops the sensor's current draw when temperature monitoring is not needed.

Frequently asked questions

What is the accuracy of the LM75BIMX-5 temperature sensor?

The ±3°C figure is the one to use for worst-case thermal margin calculations.
