1.1 Description

The TPA3004D2 audio power amplifier evaluation module is a 12-watt per

channel class-D stereo audio power amplifier complete with a small number

of external components mounted on a circuit board that measures

approximately 2-1/4 inches by 1-3/4 inches (Figure 1–1 and Figure 1–2).

The TPA3004D2 can be interfaced with the TPA6110A2 to provide additional

headphone drive. The TPA3004D2 has an internal 5-V supply to power the

TPA6110A2, and thevariableoutputs of the TPA3004D2 are usedtodrive the

inputs of the TPA6110A2.
