Local temperature is reported with 9-bit resolution, while the remote channel uses 10-bit resolution — the extra bit on the remote side gives finer granularity for the external sense point, which is typically the critical junction you are actually trying to protect. Accuracy is specified as ±3°C over the 0°C to 85°C test condition range, which covers the majority of equipment-ambient and board-temperature monitoring scenarios. Operating temperature is rated 0°C to 115°C, with the local and remote sensing ranges both specified at 0°C to 85°C. The wider operating ceiling (115°C) means the chip itself can survive hotter spots on the board, but the measurement accuracy is guaranteed only within the 0°C to 85°C sensing window. ## Feature set for system integration Built-in features include One-Shot conversion (for a single reading on demand without continuous polling), Programmable Resolution (to trade off conversion time vs precision), Shutdown Mode (to drop power when not measuring), and Standby Mode (to keep the SMBus alive while idling the conversion engine). The SMBus output type means the sensor connects directly to a two-wire bus shared with other devices — no extra GPIOs needed on the host controller, just the clock and data lines with pull-up resistors. Available in Tape & Reel (TR) or Cut Tape (CT) quantities, so prototype builds can order a few pieces without committing to a full reel.","metaTitle":"LM95221CIMM/NOPB Texas Instruments Digital Temp Sensor","metaDescription":"Texas Instruments LM95221CIMM/NOPB digital local/remote temperature sensor, SMBus output, ±3°C accuracy, 8-VSSOP package.
