TPA3132D2RHBR from Texas Instruments, in a VQFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 PLIMIT input Power limit level adjust input; connect resistor divider from GVDD to GND or directly to GVDD for no power limit.
2 GVDD power_out Internally generated gate voltage supply; connect only 1µF X7R ceramic decoupling capacitor to this pin.
3 GAIN/SLV input Gain selection and Master/Slave sync mode input determined by voltage divider.
4 GND power_in Ground.
5 INNL input Negative audio input for left channel, internally biased at 3V.
6 INPL input Positive audio input for left channel, internally biased at 3V.
7 MUTE input Mute control input; HIGH disables outputs (high-Z), LOW enables outputs, TTL logic levels.
8 AM2 input AM avoidance frequency selection bit 2; used with AM0 and AM1 to select switching frequency.
9 AM1 input AM avoidance frequency selection bit 1; used with AM0 and AM2 to select switching frequency.
10 AM0 input AM avoidance frequency selection bit 0; used with AM1 and AM2 to select switching frequency.
11 SYNC bidirectional Clock input/output for multi-device synchronization; direction determined by GAIN/SLV pin, input signal not to exceed 7V.
12 AVCC power_in Analog power supply input.
13 PVCC power_in Power supply input.
14 PVCC power_in Power supply input.
15 BSPL output Bootstrap supply for positive left channel output stage; connect 220nF X7R ceramic capacitor to OUTPL.
16 OUTPL output Positive left channel audio output.
17 GND power_in Ground.
18 OUTNL output Negative left channel audio output.
19 BSNL output Bootstrap supply for negative left channel output stage; connect 220nF X7R ceramic capacitor to OUTNL.
20 GND power_in Ground.
21 GND power_in Ground.
22 BSNR output Bootstrap supply for negative right channel output stage; connect 220nF X7R ceramic capacitor to OUTNR.
23 OUTNR output Negative right channel audio output.
24 GND power_in Ground.
25 OUTPR output Positive right channel audio output.
26 BSPR output Bootstrap supply for positive right channel output stage; connect 220nF X7R ceramic capacitor to OUTPR.
27 PVCC power_in Power supply input.
28 PVCC power_in Power supply input.
29 SDZ input Shutdown control input; LOW sets outputs to high-Z, HIGH enables outputs, TTL logic levels.
30 FAULTZ output Fault reporting output; HIGH for normal operation, LOW for fault condition.
31 INPR input Positive audio input for right channel, internally biased at 3V.
32 INNR input Negative audio input for right channel, internally biased at 3V.
33 Thermal Pad power_in Exposed thermal pad for heat dissipation; connect to GND for optimal performance or leave floating if unused.
