10 mV/°C analog output — what it means on the board
The TC1047AVNBTR is an analog local temperature sensor from Microchip Technology that outputs a voltage proportional to temperature at 10 mV/°C. At 25°C the output sits at 750 mV typical, scaling linearly to 1.75 V at 125°C and 0.1 V at -40°C. That means a 10-bit ADC with a 2.5 V reference resolves about 0.25°C per LSB — enough for board-level thermal monitoring without an I²C or SPI bus.
Housed in a standard SOT-23-3 (SC-59) package — three pins, 0.95 mm pitch, 2.9 mm body length. The footprint matches the common SOT-23 layout used by dozens of analog sensors and passives, so a last-minute swap from a different vendor's part is usually a BOM-line change, not a board spin.
