    TAS5624A 150-W Stereo and 300-W Mono PurePath HD Digital Input Class-D PowerStage

    1 Features 3 DescriptionThe TAS5624A device is a thermally-enhanced

    1 PurePath HD Integrated Feedback Provides:version of the class-D power amplifier based on the 0.025% THD at 1 W into 4 TAS5614A using large MOSFETs for improved power

    > 65-dB PSRR (No Input Signal) efficiency and a novel gate-drive scheme for reducedlosses in idle and at low-output signals leading to > 105-dB (A-Weighted) SNRreduced heat sink size. Preclipping Output for Control of a Class-G PowerThe unique preclipping output signal can be used toSupplycontrol a Class-G power supply. This combined with Reduced Heat Sink Size Due to Use of 40-mthe low idle loss and high power efficiency of theOutput MOSFET With > 90% Efficiency at Full TAS5624A leads to industry leading levels ofOutput Power efficiency ensuring a super green system.

    Output Power at 10% THD+NThe TAS5624A uses constant voltage gain. The 150-W and 4- BTL Stereo Configuration internally-matched gain resistors ensure a high power

    300-W and 2- PBTL Mono Configuration supply rejection ratio giving an output voltage onlydependent on the audio input voltage and free from Output Power at 10% THD+Nany power supply artifacts. 125-W and 4- BTL Stereo ConfigurationThe high integration of the TAS5624A makes the 250-W and 2- PBTL Mono Configurationamplifier easy to use; and, using TIs reference Click-Free and Pop-Free Start-Up schematics and PCB layouts leads to fast design in

    Error Reporting Self-Protected Design With UVP, time. The TAS5624A is available in the space-saving,Overtemperature, and Short-Circuit Protection surface-mount 44-pin HTSSOP package.
