The TC1046 is a linear output temperature sensor that outputs a voltage directly proportional to the measured temperature; the TC1046 can accurately measure temperatures from -40°C to +125°C. The output voltage range of these devices is typically 174 mV at -40°C, 424 mV at 0°C, 580 mV at +25°C, and 1205 mV at +125°C. The output voltage range of these devices is typically 174mV at -40°C, 424mV at 0°C, 580mV at +25°C, and 1205mV at +125°C. The voltage slope of 6.25mV/°C allows for a wide temperature range.
