It resolves temperature to 15 bits and delivers a typical accuracy of ±0.5°C across the full operating range of -55°C to 150°C. That range covers everything from cold-start avionics to hot-side industrial enclosures, so it is a natural fit for thermal management in base stations, power supplies, and automotive engine-bay monitoring where the ambient can spike well past 105°C. ## Accuracy and the ±0.5°C claim The ±0.5°C figure is the highest accuracy grade; the lowest is ±0.7°C. That ±0.5°C is maintained over the -40°C to 105°C test window, which is the practical range for most equipment. Outside that window the sensor still operates but the error may drift toward the ±0.7°C limit. For a thermal-shutdown threshold or a fan-control loop, ±0.5°C is tight enough to avoid nuisance trips while keeping the margin slim. ## Built-in features: One-Shot, Output Switch, Shutdown Mode The One-Shot command lets the host take a single temperature reading then put the part back into shutdown, cutting average current in battery-powered or duty-cycled designs. The Output Switch can be configured as a comparator or event-triggered alarm — it pulls low when the temperature crosses a programmable threshold, so it can drive a fault LED or an interrupt pin directly. Shutdown Mode drops the supply current to near-zero between reads. ## Package and storage The part comes in an 8-TDFN package measuring 3 mm by 3 mm (supplier device package 8-TDFN 3x3) with an exposed pad for thermal coupling to the PCB. It ships in a Tube. The exposed pad should be soldered to a ground plane for best thermal transfer — that is how the sensor tracks the board temperature rather than its own self-heating. Store the reels dry; the TDFN package is moisture-sensitive and needs a dry cabinet or a bake before reflow if the seal is broken. ## Lifecycle and sourcing position No end-of-life notice or last-time-buy window has been announced. For a BOM line that needs a precision local temperature sensor with wide temperature range, this part is safe to qualify into new designs.","metaTitle":"MAX31725MTA+ Digital Temperature Sensor, ±0.5°C Accuracy","metaDescription":"MAX31725MTA+ digital local temperature sensor from Analog Devices. ±0.5°C accuracy, I²C output, -55°C to 150°C range.
