Description
ThePI3USB223combinesACcoupledaudiosignalsandUSB2.0
HS(480Mbps)onthesamepins.Thisenablesuserstouseasingle
connectortodriveeitheraUSBendpointoranaudioendpoint.
PI3USB223incorporatesgatepumptechnologyrequiredtomain-
tainlowRonforidealaudioTHDwhilereducingthecapacitance
affectofhighspeedUSBsignals.Thedevicealsoincorporatesa
substratepumptechnologywhichallows-2Vsignalstopassthrough
theswitchwithoutcausinganyleakage.
ThePI3USB223featuresprotectiononD+/RandD-/Ltoensureno
damagewillhappentotheICifthesepinsareshortedaccidentally
toVbusaswellasensuringthereisnoleakagewhenVDDisonor
off.Also,itincludesVBUSdetection(VB)toautomaticallyswitch
totheUSBsignalpathupondetectionofavalidVBUSsignal.It
alsofeaturesinternalshuntresistorsontheaudiopathtoreduce
clicksandpopsheardduringoutput.Thedeviceisavailableina
space-saving10-pin,1.4mmx1.8mmUQFNpackage,andoperate
overthe-40°Cto+85°Ctemperaturerange.
