Electrical Characteristics for Single-Ended Operation (Notes 3, 15) (Continued)
Note 18: The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 19: Output power is measured at the device terminals.
Note 20: When driving 3
or 4 loads and operating on a 5V supply, the LM4873LQ must be mounted to a circuit board that has a minimum of 2.5in2 of exposed,
uninterrupted copper area connected to the LLP package’s exposed DAP.

Note 21: This curve shows the LM4873MTE’s and the LM4873LQ’s thermal dissipation ability at different ambient temperatures given these conditions:
500LFPM + JEDEC board: The part is soldered to a 1S2P 20-lead exposed-DAP TSSOP test board with 500 linear feet per minute of forced-air flow across it.
Board information - copper dimensions: 74x74mm, copper coverage: 100% (buried layer) and 12% (top/bottom layers), 16 vias under the exposed-DAP.
