TPA3113D2PWPR from Texas Instruments, in a HTSSOP-28. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SD input Active-low shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with compliance to AVCC.
2 FAULT output Open-drain output used to display short circuit or DC detect fault status. Voltage compliant to AVCC. Short-circuit faults can be set to auto-recovery by connecting FAULT pin to SD pin; otherwise reset by cycling PVCC.
3 LINP input Positive audio input for left channel. Biased at 3 V.
4 LINN input Negative audio input for left channel. Biased at 3 V.
5 GAIN0 input Gain select least significant bit. TTL logic levels with compliance to AVCC.
6 GAIN1 input Gain select most significant bit. TTL logic levels with compliance to AVCC.
7 AVCC power_in Analog supply. Operating range 8 V to 26 V (30 V absolute max).
8 AGND power_in Analog signal ground. Connect to the thermal pad.
9 GVDD power_out High-side FET gate drive supply. Nominal voltage is 7 V (6.4-7.4 V). Also should be used as supply for PLIMIT.
10 PLIMIT input Power limit level adjust. Connect a resistor divider from GVDD to GND to set the power limit. Connect directly to GVDD for no power limit.
11 RINN input Negative audio input for right channel. Biased at 3 V.
12 RINP input Positive audio input for right channel. Biased at 3 V.
13 NC unconnected Not connected.
14 PBTL input Parallel BTL mode switch. Selects between stereo BTL (2x BTL) and mono PBTL operation.
15 PVCCR power_in Power supply for right channel H-bridge. Right channel and left channel power supply inputs are connected internally. 8 V to 26 V.
16 PVCCR power_in Power supply for right channel H-bridge. Right channel and left channel power supply inputs are connected internally. 8 V to 26 V.
17 BSPR passive Bootstrap I/O for right channel, positive high-side FET. External bootstrap capacitor connection for high-side gate drive.
18 OUTPR output Class-D H-bridge positive output for right channel.
19 PGND power_in Power ground for the H-bridges.
20 OUTNR output Class-D H-bridge negative output for right channel.
21 BSNR passive Bootstrap I/O for right channel, negative high-side FET. External bootstrap capacitor connection.
22 BSNL passive Bootstrap I/O for left channel, negative high-side FET. External bootstrap capacitor connection.
23 OUTNL output Class-D H-bridge negative output for left channel.
24 PGND power_in Power ground for the H-bridges.
25 OUTPL output Class-D H-bridge positive output for left channel.
26 BSPL passive Bootstrap I/O for left channel, positive high-side FET. External bootstrap capacitor connection.
27 PVCCL power_in Power supply for left channel H-bridge. Right channel and left channel power supply inputs are connected internally. 8 V to 26 V.
28 PVCCL power_in Power supply for left channel H-bridge. Right channel and left channel power supply inputs are connected internally. 8 V to 26 V.
29 PowerPAD power_in Exposed thermal pad on the underside of the chip. Connect to ground and to a thermally dissipating plane for proper power dissipation.
