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 for a predictable temperature

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.
