6.7 Electrical Characteristics: LM35, LM35C, LM35D Limits

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.

(1)

Tested Limits are ensured and 100% tested in production.

(2)

Design Limits are ensured (but not 100% production tested) over the indicated temperature and supply voltage ranges. These limits are

not used to calculate outgoing quality levels.

(3)

Accuracy is defined as the error between the output voltage and 10 mv/°C times the case temperature of the device, at specified

conditions of voltage, current, and temperature (expressed in °C).

(4)

Non-linearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight line, over the rated

temperature range of the device.

(5)

Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output due to heating

effects can be computed by multiplying the internal dissipation by the thermal resistance.

(6)

Quiescent current is defined in the circuit of Figure 14.
