产品描述

The LM50/LM50-Q1 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/LM50-Q1’s output voltage is linearly proportional to Celsius (Centigrade) temperature (+10 mV/°C) and has a DC offset of +500 mV. The offset allows reading negative temperatures without the need for a negative supply. The ideal output voltage of the LM50/LM50-Q1 ranges from +100 mV to +1.75V for a −40°C to +125°C temperature range. The LM50/LM50-Q1 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/LM50-Q1 at the wafer level assure low cost and high accuracy. The LM50/LM50-Q1’s linear output, +500 mV offset, and factory calibration simplify circuitry required in a single supply environment where reading negative temperatures is required. Because the LM50/LM50-Q1's quiescent current is less than 130 ’A, self-heating is limited to a very low 0.2°C in still air.
