TPA6132A2RTER from Texas Instruments, in a WQFN-16-EP(3x3). 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 | INL- | input | Inverting left input for differential signals; left input for single-ended signals. Input range 0 V to HPVDD+0.3 V. |
| 2 | INL+ | input | Non-inverting left input for differential signals. Connect to ground for single-ended input applications. |
| 3 | INR+ | input | Non-inverting right input for differential signals. Connect to ground for single-ended input applications. |
| 4 | INR- | input | Inverting right input for differential signals; right input for single-ended signals. |
| 5 | OUTR | output | Right headphone amplifier output. Connect to right terminal of headphone jack. DirectPath biased at 0 V DC. |
| 6 | G0 | input | Gain select bit 0. Logic input: VIH ≥ 1.3 V, VIL ≤ 0.6 V. Combined with G1 selects one of four gain settings: -6, 0, 3, or 6 dB. |
| 7 | G1 | input | Gain select bit 1. Logic input: VIH ≥ 1.3 V, VIL ≤ 0.6 V. Combined with G0 selects one of four gain settings: -6, 0, 3, or 6 dB. |
| 8 | HPVSS | power_out | Charge pump output and negative power supply for output amplifiers. Connect 1 µF capacitor to GND. Generated internally by the charge pump to enable DirectPath ground-referenced outputs. |
| 9 | CPN | passive | Charge pump negative flying capacitor. Connect to negative side of 1 µF flying capacitor between CPP and CPN. |
| 10 | PGND | power_in | Power ground for the charge pump and output stage. |
| 11 | CPP | passive | Charge pump positive flying capacitor. Connect to positive side of 1 µF flying capacitor between CPP and CPN. |
| 12 | HPVDD | power_in | Positive power supply for headphone amplifiers (max 1.9 V; internally regulated). Connect 2.2 µF decoupling capacitor. Do NOT connect to VDD or an external supply. |
| 13 | EN | input | Amplifier enable. Connect logic low to shutdown (<1 µA supply); connect logic high (VIH ≥ 1.3 V) to activate the amplifier. |
| 14 | VDD | power_in | Positive power supply for TPA6132A2. Operating range 2.3 V to 5.5 V; absolute max 6 V. Typical supply current 2.1 mA. |
| 15 | SGND | power_in | Signal ground / amplifier reference voltage. Connect to ground terminal of headphone jack. |
| 16 | OUTL | output | Left headphone amplifier output. Connect to left terminal of headphone jack. DirectPath biased at 0 V DC. |
| 17 | PAD | passive | Exposed thermal pad on the bottom of the QFN package. Solder to the PCB landing pad. Connect the landing pad to ground or leave electrically floating (unconnected). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 593 faces against 110 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
