NCT47 High Precision Temperatureto-
Voltage Converter
The NCT47 is linear output temperature sensor whose output
voltage is directly proportional to measured temperature. The NCT47 can accurately measure temperature from –40°C to +125°C. For the NCT47, the output
voltage range is typically 100mV at –40°C, 500mV at 0°C, 750mV at +25°C, and 1.75V at +125°C. A 10mV/°C
voltage slope allows for the wide temperature range. The NCT47 is packaged in space saving 3–Pin SOT–23B packages, making them ideal for space critical applications.
