Power and temperature

How hot is too hot? Does my circuit need a heat sink?

This series discusses the relationship between power dissipation and temperature in op amps and shows how to calculate an amplifier's junction temperature under a variety of operating conditions using its thermal model. Absolute maximum ratings and internal thermal protection schemes are also introduced.
