Clinical-grade temperature sensing in a compact digital package
The MAX30205MTA+ is a digital local temperature sensor from Analog Devices that converts the die temperature directly to a 16-bit digital word over an I²C-compatible serial interface. Its headline ±0.1°C accuracy over the 0°C to 50°C range makes it a natural fit for medical thermometry, wearable health monitors, and clinical-grade temperature logging where the measurement must be trusted without external calibration.
What the ±0.1°C accuracy means for your BOM
The ±0.1°C accuracy (highest) and ±0.5°C (lowest) are specified across the 0°C to 50°C range.
Package and integration notes
The 8-TDFN exposed pad package (3x3 mm) requires a thermal land on the PCB to draw heat from the die — the exposed pad is the primary thermal path, not just a mechanical anchor. The I²C bus runs at standard or fast mode; the output switch and programmable limit features let the part assert an interrupt or alarm pin without polling the bus continuously, which saves firmware cycles in a multi-sensor system.
Lifecycle and compliance
The MAX30205MTA+ carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect, so it can be specified into new production runs without an obsolescence watch.
