TPA4411RTJR from Texas Instruments, in a QFN-20-EP(4x4). 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 | C1P | bidirectional | Positive terminal of the charge pump flying capacitor. |
| 2 | PGND | power_in | Power ground; connect to ground. |
| 3 | C1N | bidirectional | Negative terminal of the charge pump flying capacitor. |
| 4 | NC | unconnected | No connection. |
| 5 | PVSS | power_out | Output from the charge pump, providing the negative supply rail for the amplifier. |
| 6 | NC | unconnected | No connection. |
| 7 | SVSS | power_in | Amplifier negative supply; connect to PVSS via a star connection. |
| 8 | NC | unconnected | No connection. |
| 9 | OUTL | output | Left audio channel output signal. |
| 10 | SVDD | power_in | Amplifier positive supply; connect to PVDD via a star connection. |
| 11 | OUTR | output | Right audio channel output signal. |
| 12 | NC | unconnected | No connection. |
| 13 | INL | input | Left audio channel input signal. |
| 14 | SDR | input | Right channel shutdown, active-low logic. |
| 15 | INR | input | Right audio channel input signal. |
| 16 | NC | unconnected | No connection. |
| 17 | SGND | power_in | Signal ground; connect to ground. |
| 18 | SDL | input | Left channel shutdown, active-low logic. |
| 19 | PVDD | power_in | Supply voltage; connect to the positive supply. |
| 20 | NC | unconnected | No connection. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
