One-shot and shutdown modes let the part sleep between readings, drawing near-zero quiescent current — useful for thermal profiling in battery-operated gear where the bus is idle most of the time.","metaTitle":"TMP103CYFFR Texas Instruments Digital Temp Sensor, ±2°C","metaDescription":"Active production digital local temp sensor from TI, ±2°C accuracy, I²C/SMBus, 1.4-3.6V supply, -55 to 150°C range.
