It measures its own die temperature across a -55°C to 150°C range — the same range as the operating temperature of the device itself, so the sensor can be placed directly in the hot zone of a PCB without derating. Accuracy is ±1.5°C typical from -10°C to 65°C, widening to ±3°C worst-case across the full range. That is enough for thermal monitoring, overtemperature protection, or fan control — not for precision calibration where ±0.5°C would be needed. ## Supply flexibility and power-down capability The Shutdown Mode feature drops the quiescent current to near zero — useful for battery-powered equipment that wakes periodically to log temperature. Package is an 8-TSSOP or 8-MSOP (3.00mm width), supplied in Bulk (not tape-and-reel). The 0.65mm pitch and small footprint fit tight layouts, but the Bulk packaging means the buyer receives tubes or trays — factor that into pick-and-place setup if your line expects reels. ## Active lifecycle, RoHS non-compliant — sourcing angle One important catch: the part is marked RoHS non-compliant. If your BOM requires RoHS exemption or full compliance for EU markets, verify the exemption status or consider the lead-free variant (LM70CIMMX-3/NOPB). We can source this part against an RFQ and confirm the date code and compliance documentation at quote time.","metaTitle":"Texas Instruments LM70CIMMX-3 Digital Temp Sensor, SPI","metaDescription":"Texas Instruments LM70CIMMX-3 digital local temperature sensor, 10-bit SPI output, -55°C to 150°C range, ±1.5°C accuracy.
