Active production, ±2°C accuracy on a 1x1 mm footprint
The TMP103GYFFT: Its ±2°C accuracy (max) from -10°C to 100°C, degrading to ±3°C outside that band, is the figure that governs measurement confidence in a calibration or monitoring loop — within the rated range you can trust the digital readout to that tolerance without external trimming.
Digital interface and power-saving modes
Output is I²C/SMBus compatible — the 8-bit digital word is read directly over the two-wire bus without an ADC channel or analog routing on the PCB. One-Shot mode lets the firmware trigger a single conversion on demand and return to shutdown, drawing near-zero quiescent current between reads — useful for battery-powered loggers that sample temperature every few seconds.
Surface-mount only; the small footprint frees board area for other components in dense sensor arrays or multi-point thermal monitoring designs.
