22 / 41 page  8 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The TPA3139D2 device is designed for use in inductor-free applications with limited distance wire length between amplifier and speakers, suitable for applications such as TV sets, sound docks and Bluetooth speakers. The TPA3139D2 device can either be configured in stereo or mono mode. Depending on the output power requirements and necessity for (speaker) load protection, the built-in PLIMIT circuit can be used to control the system power, see functional description of these features. 8.2 Typical Applications S1 SHUTDOWN 100k R9 PVCC GND GND LINP RINN RINP TP3 LINP 4 3 1 J4 LIN PVCC PVCC 1uF 35V C1 GND GND GND PVCC GND GND GND GND TP4 LINN GND 4 3 1 J9 RIN TP8 RINN 100k R6 PLIMIT ADJ 10.0k R5 GND TP6 PLIMIT GND LINP LINN RINP RINN PLIMIT GAIN_SEL SD/FAULT OUTPL OUTNL OUTNR OUTPR 1000pF 100V C6 1000pF 50V C7 OUTL+ OUTL- OUTR- OUTR+ GND GND OUTPL GND 1000pF 100V C13 1000pF 50V C14 GND GND GND 1000pF 100V C22 1000pF 50V C23 GND GND GND 1000pF 100V C27 1000pF 50V C28 GND GND GND OUTPR OUTNL MODE_SEL OUTNR 330pF 50V C26 330pF 50V C21 330pF 50V C12 330pF 50V C5 LINN TP7 RINP TP9 SHUTDOWNz TP5 GVDD PVCCL PVCCR PVCC GND IN = 20dB Gain OUT = 26dB Gain 100k R12 PVCC GND IN = BD OUT = Low Idle Current 100k R13 J6 LGND J10 RGND J13 GAIN SEL J14 MODE SEL J7 L2 L6 L4 L5 0.22uF 25V C17 0.22uF 25V C18 0.22uF 25V C19 0.22uF 25V C20 1uF 35V C16 1uF 35V C11 1uF 35V C15 1uF 35V C24 1uF 35V C25 GND MUTE 15 SDZ/FAULT 4 LINP 5 LINN 6 MOD_SEL 8 GAIN_SEL 7 AGND 10 GVDD 11 RINN 13 RINP 14 PLIMIT 12 AVCC 9 PVCCL 3 PVCCR 16 BSPR 17 OUTPR 18 PGND 19 OUTNR 20 BSNR 21 BSNL 22 OUTNL 23 PGND 24 OUTPL 1 BSPL 2 PAD 25 U1 TPA3139D2RGE 100uF 50V C2 1000pF 50V C4 25V 0.1uF C3 100uF 50V C8 1000pF 50V C10 25V 0.1uF C9 L1 L3 S2 MUTE 100k R14 PVCC GND MUTE PLIMIT Q1 GND PVCC 200k R15 10.0 R1 68.0 R2 10.0 R3 10.0 R7 10.0 R10 68.0 R4 68.0 R8 68.0 R11 Figure 8-1.
