Typical Applications

Figure 2. Basic Centigrade Temperature Sensor (+2.5°C to +100°C)

= +250 mV at +25°C

=

−200 mV at −20°C

−20°C to +100°C)

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Operating Temperature Range

LM45B, LM45C

−40°C to +125°C

+4.0V to +10V

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not

apply when operating the device beyond its rated operating conditions.

(2)

Soldering process must comply with Reflow Temperature Profile specifications. Refer to http://www.ti.com/packaging.

(3)

Reflow temperature profiles are different for lead-free and non-lead-free packages.

(4)

Thermal resistance of the SOT-23 package is 260°C/W, junction to ambient when attached to a printed circuit board with 2 oz. foil as

shown in Figure 15.
