TPA6133A2RTJR 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 | LEFTINM | input | Left channel negative differential input; impedance must be matched to LEFTINP. |
| 2 | LEFTINP | input | Left channel positive differential input; impedance must be matched to LEFTINM. |
| 3 | GND | power_in | Analog ground; must be connected to common supply GND. |
| 4 | RIGHTINP | input | Right channel positive differential input; impedance must be matched to RIGHTINM. |
| 5 | RIGHTINM | input | Right channel negative differential input; impedance must be matched to RIGHTINP. |
| 6 | SD | input | Shutdown control; active low logic, 5V tolerant input. |
| 7 | TEST2 | input | Factory test pin; pull up to VDD supply. |
| 8 | TEST1 | input | Factory test pin; pull up to VDD supply. |
| 9 | GND | power_in | Analog ground; must be connected to common supply GND. |
| 10 | GND | power_in | Analog ground; must be connected to common supply GND. |
| 11 | HPRIGHT | output | Right channel headphone amplifier output; connect to right terminal of headphone jack. |
| 12 | VDD | power_in | Analog power supply; must be decoupled with 1-μF capacitor to pin 13. |
| 13 | GND | power_in | Analog ground; recommended for decoupling pin 12 VDD. |
| 14 | HPLEFT | output | Left channel headphone amplifier output; connect to left terminal of headphone jack. |
| 15 | CPVSS | power_out | Negative supply generated by charge pump; decouple to pin 19 or GND plane with 1-μF capacitor. |
| 16 | CPVSS | power_out | Negative supply generated by charge pump; decouple to pin 19 or GND plane with 1-μF capacitor. |
| 17 | CPN | passive | Charge pump flying capacitor negative terminal; connect one side of flying capacitor. |
| 18 | CPP | passive | Charge pump flying capacitor positive terminal; connect one side of flying capacitor. |
| 19 | GND | power_in | Charge pump ground; must be connected to common supply GND and decoupled to pin 20. |
| 20 | VDD | power_in | Charge pump voltage supply; must be decoupled with 1-μF capacitor to pin 19. |
| 21 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
