TC1047/TC1047A
Precision Temperature-to-Voltage Converter
Features General Description Supply Voltage Range:
-TC1047: 2.7V to 4.4V
-TC1047A: 2.5V to 5.5V Wide Temperature Measurement Range:
-40oC to +125oC High Temperature Converter Accuracy:
-В± 2oC, Max, at 25В°C Linear Temperature Slope: 10 mV/В°C (typ.) Available in 3-Pin SOT-23B Package Very Low Supply Current:
-35 ВµA Typical The TC1047 and TC1047A are linear voltage output
temperature sensors whose output voltage is directly
proportional to the measured temperature. The
TC1047 and TC1047A can accurately measure
temperature from -40В°C to +125В°C. With the TC1047,
the supply voltage can vary between 2.7V and 4.4V.
The power supply range of the TC1047A is from 2.5V
to 5.5V. Applications Cellular Phones
Power Supply Thermal Shutdown
Temperature-Controlled Fans
Temperature Measurement/Instrumentation
Temperature Regulators
Consumer Electronics
Portable Battery-Powered Equipment The output voltage range for these devices is typically
100 mV at -40В°C, 500 mV at 0В°C, 750 mV at +25В°C and
1.75V at +125В°C. A 10 mV/В°C voltage slope output …
