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