TEXAS INSTRUMENTS LM50BIM3/NOPB

The LM50BIM3/NOPB is a ±2°C analogue output Temperature Sensor that can sense a -40 to +125°C temperature range using a single positive supply. The LM50's output voltage is linearly proportional to Celsius (Centigrade) temperature (+10mV/°C) and has a DC offset of +500mV. The offset allows reading negative temperatures without the need for a negative supply. Trimming and calibration of the temperature sensor at the wafer level assure low cost and high accuracy. This temperature sensor features linear output, +500mV offset and factory calibration simplify circuitry required in a single supply environment where reading negative temperatures is required. Because the sensor quiescent current is less than 130A, self-heating is limited to a very low 0.2°C in still air.
