Figure 3. Maximum Power Dissipation vs. Temperature

Airflow increases heat dissipation, effectively reducing θJA. Also, more metal directly in contact with the package

leads from metal traces, through holes, ground, and power planes reduce the θJA.

Figure 3 shows the maximum safe power dissipation in the package vs. the ambient temperature for the SOIC-8

(125°C/W) package on a JEDEC standard 4-layer board. θJA values are approximations.

ESD Caution

ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can

discharge without detection. Although this product features patented or proprietary

protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore,

proper ESD precautions should be taken to avoid performance degradation or loss of

functionality.
