TC1046VNBTR Microchip

TC1046 High Precision Temperature-to-Voltage Converter Features General Description Supply Voltage Range: 2.7V to 4.4V The TC1046 is a linear output temperature sensor whose output voltage is directly proportional to Wide Temperature Measurement Range: o measured temperature. The TC1046 can accurately -40 C to +125 C measure temperature from -40C to +125C. High Temperature Converter Accuracy: o 2 C, Max, at 25C The output voltage range for these devices is typically o 174mV at -40C, 424mV at 0C, 580 mV at +25C, and Linear Temperature Slope: 6.25mV/ C 1205mV at +125C. A 6.25mV/C voltage slope allows Very Low Supply Current: 35 A Typical for the wide temperature range. Small 3-Pin SOT-23B Package The TC1046 is packaged in a 3-Pin SOT-23B package, making them ideal for space critical applications.
