NCT47
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. http://onsemi.com • • • • • • Features Wide Temperature Measurement Range: –40°C to 125°C High Temperature Converter Accuracy: ±2°C Max at 25°C Linear Temperature Slope: 10mV/°C 2.7V to 4.4V Operating Range Small 3–Pin SOT–23B Package Very Low Supply Current: 35µA typical SOT–23B (TO–236) CASE TBD PIN CONFIGURATION (Top View) VDD 1 VSS Typical Applications • Cellular Phones • Power Supply Thermal Shutdown • Temperature–Controlled Fans • Temperature Measureme.
