1 Introduction

The TAS5622-TAS5624DDVEVM PurePath™ EVM demonstratesthecurrentversionofTAS5622DDV or TAS5624DDV integratedcircuitpower stagewithTAS5538DGG fromTexas Instruments(TI). The TAS5622 and TAS5624 arehigh-performance,integratedStereoFeedback DigitalAmplifierPower Stagesdesignedtodrive3Ω speakersatup to200W perchannelforTAS5624DDV and 165W per channelforTAS5622DDV. They requireonlya passivedemodulationfiltertodeliverefficienthighquality audioamplification. TAS5538DGG isa highperformance32 bit(24bitinput)multichannelPurePath™ DigitalPulseWidth Modulator(PWM) withfullysymmetricalAD modulationscheme. The devicealsohas DigitalAudio Processing(DAP) thatprovides48 bitsignalprocessing,advanced performanceand a highlevelof systemintegration. ThisEVM can be configuredas 2 BTL channelsforstereoevaluationor1 PBTL (parallelBTL) channelfor subwooferevaluation.Togetherwitha TIInput-USBBoard 3,itprovidesa completestereodigitalaudio amplifiersystemwhichincludesdigitalinput(S/PDIF),analoginputs,interfacetoPC and DAP features likedigitalvolume control,inputand outputmixers,automute,tonecontrols,loudness,EQ filtersand dynamicrangecompression(DRC).Thereareconfigurationoptionsforpower stagefailureprotection. NOTE: TAS5622-TAS5624DDVEVM ISSHIPPED WITH THE CURRENT VERSION OF TAS5624 INSTALLED. TO EVALUATE THE CURRENT VERSION OF TAS5622 PLEASE VISITTHE PRODUCT FOLDER AT www.ti.com AND REQUEST A FREE SAMPLE, AND REPLACE TAS5624 WITH TAS5622.

www.ti.com QuickSetupGuide CAUTION Failureto observe ESD handlingprocedurescan resultin damage to EVM components.

2.2 Unpacking theEVM

Upon openingtheTAS5622-TAS5624DDVEVM package,checktomake surethatthefollowingitemsare included:

1 pc.TAS5622-TAS5624DDVEVM using1 TAS5538DGG and 1 TAS5622DDV orTAS5624DDV.
1 pc.TIInput-USBBoard 3 forinterfacingTAS5622-TAS5624DDVEVM toSPDIF/analogsourcesand PC forcontrol.
1 pc.Signaland ControlInterfaceIDC cableforconnectiontoan I2S front-endliketheInput-USB Board 3.
1 pc.CableforconnectingInput-USBBoard 3 toa USB porton a PC forTAS5538 controlby software.
Ifany oftheseitemsaremissing,contactthenearestTexas InstrumentsProductInformationCenterto inquireabouta replacement. ConnecttheInput-USBBoard 3 totheTAS5622/14LDDVEVM usingthedeliveredIDC cable.

2.3 Power Supply Setup

2 power suppliesareneeded topower theTAS5622-TAS5624DDVEVM. Voltageand current requirementsforthePVDD power supplyareshown inthetablebelow.Connectthispower supplytothe EVM usingbanana cablesorwiressecuredtothepower supplybindingpostsPVDD and GND. A second power supply,12Vdc at500mA, isrequiredtopower Input-USBBoard 3.Connectthe12V power supply totheInput-USBBoard 3 usingbanana cablesorwiressecuredtothepower supplybindingposts+12V and GND. Table2.Recommended PVDD Power Supply Voltages Description VoltageRange CurrentRequirements BindingPost TAS5624 Power SupplyVoltage 12 -38 Vdc 20 A PVDD TAS5622 Power SupplyVoltage 12 -34 Vdc 18 A PVDD CAUTION NOTE: Applyingvoltagesabove specificationsinTable2 can cause permanent damage to the hardware.Verifypolarityof power supplyconnectionsbefore poweringtheEVM. NOTE: The lengthofthepower supplycablemust be minimized.IncreasinglengthofPSU cableis likelytoincreasedistortionfortheamplifierathighoutputlevelsand lowfrequencies.

2.4 Speaker Connection

Both positiveand negativespeaker outputsare floatingand cannot be connectedtoground (e.g.throughan oscilloscope).To measure a BTL output connectan oscilloscopeprobetoeach sideoftheoutput,connectbothground clipsto EVM ground and use the oscilloscopemath functionsto show the differencebetween the2 probesignals. 7SLAU376 –May 2012 TAS5622-TAS5624DDVEVM SubmitDocumentationFeedback Copyright© 2012,Texas InstrumentsIncorporated
