TC1046

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