Product details

Active production with ±0.75°C accuracy

The TMP108AIYFFT: It communicates over an SMBus digital interface with 11-bit resolution, making it suitable for precision thermal monitoring in portable and embedded systems where a direct digital readout replaces an analog thermistor path.

Supply voltage and temperature envelope

Operating from a 1.4V to 3.6V supply rail, the sensor runs directly off a Li-ion cell or a 1.8V/3.3V regulated bus without an additional LDO. The 6-DSBGA package (0.9 mm × 1.4 mm typical) demands a controlled reflow profile per the MSL rating, but the small footprint fits dense PCBs where board space is at a premium.

Feature set for power-aware designs

Programmable limit registers allow the sensor to assert an alert on the SMBus without polling, reducing host processor overhead. One-shot and shutdown/standby modes drop quiescent current between readings, critical for battery-powered IoT nodes that wake briefly to log temperature then sleep. The output switch feature lets the sensor drive a logic-level signal directly, eliminating an external comparator in simple over-temperature protection circuits.

Frequently asked questions

Does TMP108AIYFFT support one-shot conversion?

Yes, the sensor includes a one-shot mode for a single temperature reading on demand, with shutdown and standby modes to minimize power between conversions.
