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.","metaTitle":"LM70CIMM-3/NOPB Digital Temp Sensor, SPI, -55°C to 150°C","metaDescription":"TI LM70CIMM-3/NOPB digital temperature sensor, SPI output, 10-bit resolution, ±1.5°C accuracy, -55°C to 150°C range, 8-VSSOP.

The base LM70CIMM (non-NOPB) may be tin-lead. Electrically and functionally they are the same sensor — same SPI interface, same 10-bit resolution, same temperature range. The /NOPB version is the current active ROHS3-compliant variant. If your assembly process requires lead-free, this is the direct drop-in."},{"question":"What is the accuracy of LM70CIMM-3/NOPB?","answer":"Typical accuracy is ±1.5°C. Worst-case limits are -2°C (low) and +3°C (high) across the full -55°C to 150°C range. For tighter tolerance, consider a calibrated sensor or a higher-grade part."},{"question":"Does LM70CIMM-3/NOPB have a shutdown mode?","answer":"Yes, shutdown mode is a listed feature. It cuts the sensor's quiescent current when the SPI interface is not actively reading the temperature register. Wake it up with a SPI transaction."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM70CIMM-3-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM70CIMM-3-NOPB when reusing this data.
