Electrical Characteristics: LM34, LM34C, and LM34D (continued)

Unless otherwise noted, these specifications apply:

−50°F ≤ TJ ≤ 300°F for the LM34 and LM34A; −40°F ≤ TJ ≤ 230°F for the

LM34C and LM34CA; and +32°F

≤ TJ ≤ 212°F for the LM34D. VS = 5 Vdc and ILOAD = 50 µA in the circuit of Full-Range

Fahrenheit Temperature Sensor; 6 Vdc for LM34 and LM34A for 230°F

≤ TJ ≤ 300°F. These specifications also apply from

5°F to TMAX in the circuit of Basic Fahrenheit Temperature Sensor (5°F to 300°F).
