www.ti.com Electrical Characteristics: LM35, LM35C, LM35D (continued)
Unless otherwise noted, these specifications apply: −55°C ≤ TJ ≤ 150°C for the LM35 and LM35A; −40°C ≤ TJ ≤ 110°C for the LM35C and LM35CA; and 0°C ≤ TJ ≤ 100°C for the LM35D. VS = 5 Vdc and ILOAD = 50 μA, in the circuit of Full-Range Centigrade Temperature Sensor. These specifications also apply from 2°C to TMAX in the circuit of Figure 14.
