TPA6133A2RTJT from Texas Instruments, in a VQFN-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 whose impedance must be matched to LEFTINP; connect it to LEFTINM when using single-ended inputs. |
| 2 | LEFTINP | input | Left channel positive differential input whose impedance must be matched to LEFTINM; AC-ground it near the signal source while keeping the matched impedance when using single-ended inputs. |
| 3 | GND | power_in | Analog ground that must be connected to common supply GND and is recommended for decoupling analog VDD. |
| 4 | RIGHTINP | input | Right channel positive differential input whose impedance must be matched to RIGHTINM; AC-ground it near the signal source while keeping the matched impedance when using single-ended inputs. |
| 5 | RIGHTINM | input | Right channel negative differential input whose impedance must be matched to RIGHTINP; connect it to RIGHTINM when using single-ended inputs. |
| 6 | SD | input | Active-low shutdown logic input that is 5 V tolerant, with VIH of 1.3 V and VIL of 0.35 V per the recommended operating conditions; logic 1 activates the headphone channels and charge pump. |
| 7 | TEST2 | input | Factory test pin that must be pulled up to the VDD supply as shown in the applications diagram. |
| 8 | TEST1 | input | Factory test pin that must be pulled up to the VDD supply as shown in the applications diagram. |
| 9 | GND | power_in | Analog ground that must be connected to common supply GND. |
| 10 | GND | power_in | Analog ground that must be connected to common supply GND. |
| 11 | HPRIGHT | output | Headphone right channel output that connects to the right terminal of the headphone jack. |
| 12 | VDD | power_in | Analog VDD that must be connected to the common VDD supply (2.5 V to 5.5 V) and decoupled with its own 1 µF capacitor to analog ground at pin 13. |
| 13 | GND | power_in | Analog ground that must be connected to common supply GND and is used to decouple pin 12 on the QFN package. |
| 14 | HPLEFT | output | Headphone left channel output that connects to the left terminal of the headphone jack. |
| 15 | CPVSS | power_out | Negative supply generated by the charge pump that must be decoupled to pin 19 or a GND plane with a 1 µF capacitor. |
| 16 | CPVSS | power_out | Negative supply generated by the charge pump that must be decoupled to pin 19 or a GND plane with a 1 µF capacitor. |
| 17 | CPN | passive | Charge pump flying capacitor negative terminal; one side of the flying capacitor connects to CPN. |
| 18 | CPP | passive | Charge pump flying capacitor positive terminal; one side of the flying capacitor connects to CPP. |
| 19 | GND | power_in | Charge pump ground that must be connected to common supply GND and decoupled to the charge pump VDD pin (pin 20). |
| 20 | VDD | power_in | Charge pump voltage supply that must be connected to the common VDD supply (2.5 V to 5.5 V) and decoupled to GND (pin 19) with its own 1 µF capacitor. |
| 21 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
