TPA3244 Evaluation Module

•

Set

S1

to the

NORMAL

position.

•

CLIP_OTWz (

ORANGE

) and FAULTz (

RED

) LEDs should be off, if the audio source is off.

NOTE:

J3/J10

and

J18/J15

can be used for differential inputs to INA/INB and INC/IND, respectively.

Using a smart phone, tablet, or PC with headphone to RCA cable, audio streaming via headphone jack
can begin once the EVM is powered up correctly with jumpers in their default state. Start the media player
of your choice and enjoy the enhanced audio performance the TPA3244 provides as a quick check of the
setup.
