TPA6139A2PWR from Texas Instruments, in a TSSOP-14. 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 | -IN_L | input | Negative input for left channel; single-ended input. |
| 2 | OUT_L | output | Left channel output; ±8-kV HBM ESD protected, capable of 25 mW into 32 Ω. |
| 3 | GND | power_in | Ground; signal and power reference. |
| 4 | MUTE | input | Active-low mute control; VIL = 38-43% PVDD, VIH = 57-66% PVDD. |
| 5 | VSS | power_out | Charge pump negative supply output. |
| 6 | CN | bidirectional | Charge pump flying capacitor negative connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | NC | unconnected | No internal connection. |
| 9 | CP | bidirectional | Charge pump flying capacitor positive connection. |
| 10 | VDD | power_in | Supply voltage; 3.0-3.6 V DC recommended operating range. |
| 11 | GND | power_in | Ground; signal and power reference. |
| 12 | GAIN | input | Gain programming pin; connect resistor to ground for 13 selectable gain values. |
| 13 | OUT_R | output | Right channel output; ±8-kV HBM ESD protected, capable of 25 mW into 32 Ω. |
| 14 | -IN_R | input | Negative input for right channel; single-ended input. |
