What this analog temperature sensor does
The Texas Instruments LM45BIM3-TI is an analog voltage output temperature sensor — it produces a DC voltage linearly proportional to the sensed temperature, so a microcontroller ADC can read the temperature directly without a digital interface. The part is listed under the Discrete Semiconductors category and carries an active lifecycle status, meaning Texas Instruments continues to manufacture it for current designs.
Compliance and sourcing note
This device is marked RoHS non-compliant, so it is not suitable for assemblies that must meet RoHS exemption-free requirements — confirm your BOM's environmental compliance before specifying it in a new build.
