TPA6139A2RGTR from Texas Instruments, in a VQFN-16-EP(3x3). 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 | OUT_L | output | Single-ended audio output for left channel; ±8-kV HBM ESD protected. |
| 2 | GND | power_in | Power ground reference. |
| 3 | GND | power_in | Power ground reference. |
| 4 | MUTE | input | Mute control input, active low; mutes outputs with >80 dB attenuation. |
| 5 | VSS | power_out | Charge pump negative supply voltage output generated by internal charge pump. |
| 6 | CN | bidirectional | Charge pump flying capacitor negative connection; 1 μF capacitor recommended. |
| 7 | NC | unconnected | No internal connection. |
| 8 | CP | bidirectional | Charge pump flying capacitor positive connection; 1 μF capacitor recommended. |
| 9 | VDD | power_in | Positive supply voltage input; connect to 3.0 V to 3.6 V. |
| 10 | GND | power_in | Power ground reference. |
| 11 | GAIN | input | Gain set programming pin with internal pull-up; connect resistor to ground for 13 programmable gain values from -1x to -10x. |
| 12 | OUT_R | output | Single-ended audio output for right channel; ±8-kV HBM ESD protected. |
| 13 | -IN_R | input | Negative audio input for right channel; common-mode input range -2 V to +2 V. |
| 14 | NC | unconnected | No internal connection. |
| 15 | NC | unconnected | No internal connection. |
| 16 | -IN_L | input | Negative audio input for left channel; common-mode input range -2 V to +2 V. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
