What this digital temp sensor brings to the board
The Texas Instruments LM70CIMM-3/NOPB is a digital local temperature sensor that reads the die temperature and reports it over a SPI interface with 10-bit resolution. It covers the full -55°C to 150°C range, making it one of the few digital sensors that stays rated all the way to 150°C — useful for under-hood automotive, industrial oven zones, or high-temp test fixtures. The SPI output means you connect it directly to any MCU or FPGA SPI port; no external ADC or signal conditioning. Accuracy is ±1.5°C typical, with worst-case bounds of -2°C / +3°C across the full range.
Package and mounting
The part comes in an 8-VSSOP (3.00 mm width) — a small-outline surface-mount package. Supply is available in Tape & Reel or Cut Tape.
Lifecycle and sourcing — active, no obsolescence worry
The LM70CIMM-3/NOPB is listed as Active and ROHS3 compliant. There is no NRND or LTB notice on this variant. For new designs, there is no end-of-life clock ticking. If you are filling a BOM line, this is a straightforward active part to qualify.
