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 reduces

the θJA. Care must be taken to minimize parasitic capacitances

at the input leads of high speed op amps as discussed in the

board layout section.

Figure 4 shows the maximum safe power dissipation in the

package vs. the ambient temperature for the SOIC-8

(125°C/W), SOT23-5 (180°C/W), and MSOP-8 (150°C/W) on a

JEDEC standard four-layer board.
