General Description
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 -40°C to +125°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.
The output voltage range for these devices 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 output
response allows
measurement over a wide temperature range. The
TC1047 and TC1047A are packaged in 3-Pin SOT-23B
packages, making them ideal for space critical
applications.
