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.
