The LMT85LPGM outputs an analog voltage that scales linearly at 8.2 mV per degree Celsius over the full -50°C to 150°C sensing range. At 25°C the output sits near 1.575 V (typical), so a 3.3 V ADC with 12-bit resolution gives you roughly 0.8°C per LSB — enough headroom to resolve the ±2.7°C accuracy spec without an external amplifier. Because the output is ratiometric to the supply, the accuracy depends on the ADC reference stability. Running the sensor from the same 3.3 V rail that feeds the MCU's VREF cancels the supply error.
AEC-Q100 Grade 0 — validated for -50°C to 150°C
The -50°C to 150°C operating range covers engine bay, transmission, and exhaust-adjacent locations where the ambient temperature can spike above 125°C. The test condition for the accuracy spec is 20°C to 150°C — the ±2.7°C figure is guaranteed across the upper part of the range where the sensor is most likely to be used in a thermal management loop.
TO-92-3 short body — through-hole for prototyping and low-volume production
The TO-92-3 short-body package (TO-226-3 variant) keeps the seated height lower than a standard TO-92, which matters when the sensor sits on a daughterboard inside a sealed enclosure. Through-hole leads are hand-solderable and socket-friendly, so the same part works for breadboard validation and the final assembly. Cut Tape is the practical choice for prototype quantities.
