The continuous power output of any amplifier is determined by the thermal performance of the amplifier as well as limitations placed on

it by the system around it, such as the PCB configuration and the ambient operating temperature. The performance characteristics listed

in this section are achievable on the TAS5760LD's EVM, which is representative of the poplular "2 Layers / 1oz Copper" PCB

configuration in a size that is representative of the amount of area often provided to the amplifier section of popular consumer audio

electronics. As can be seen in the instantaneous power portion of this table, more power can be delivered from the TAS5760LD if steps

are taken to pull more heat out of the device. For instance, using a board with more layers or adding a small heatsink will result in an

increase of continuous power, up to and including the instantaneous power level. This behavior can also been seen in the POUT vs.

PVDD plots shown in the typical performance plots section of this data sheet.
