LM50C
Description
The LM50 is a precision integrated-circuit temperature sensor that can sense a
- 40˚C to +125˚C temperature range using a single positive supply. The LM50’s output voltage is linearly proportional to Celsius (Centigrade) temperature (+10 m V/˚C) and has a DC offset of +500 m V. The offset allows reading negative temperatures without the need for a negative supply. The ideal output voltage of the LM50 ranges from +100 m V to +1.75V for a
- 40˚C to +125˚C temperature range. The LM50 does not require any external calibration or trimming to provide accuracies of ± 3˚C at room temperature and ± 4˚C over the full
- 40˚C to +125˚C temperature range. Trimming and calibration of the LM50 at the wafer level assure low cost and high accuracy. The LM50’s linear output, +500 m V offset, and factory calibration simplify circuitry required in a single supply environment where reading negative temperatures is required. Because the LM50’s quiescent current is less than 130 µA, self-heating is...
