Texas Instruments · Audio Power OpAmps · QFN-20-EP(4x4)

TPA6130A2RTJR from Texas Instruments, in a QFN-20-EP(4x4). 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 LEFTINM input Left channel negative differential audio input. Impedance must be matched to LEFTINP. In single-ended mode, connect the left source to LEFTINM.
2 LEFTINP input Left channel positive differential audio input. Impedance must be matched to LEFTINM. In single-ended mode, AC-ground LEFTINP near the source while maintaining matched impedance.
3 GND power_in Analog ground. Connect to common supply GND. Used to decouple analog VDD.
4 RIGHTINP input Right channel positive differential audio input. Impedance must be matched to RIGHTINM. In single-ended mode, AC-ground RIGHTINP near the source while maintaining matched impedance.
5 RIGHTINM input Right channel negative differential audio input. Impedance must be matched to RIGHTINP. In single-ended mode, connect the right source to RIGHTINM.
6 SD input Shutdown input. Active-low; drive high to enable the device, low to place it in hardware shutdown (IDD ≤1 µA typ). 5 V-tolerant logic input (VIH ≥1.3 V, VIL ≤0.35 V).
7 SDA bidirectional I2C serial data. Open-drain, 5 V-tolerant. Requires an external pull-up (≤2 kΩ for a 5 V bus). Standard/Fast mode up to 400 kHz.
8 SCL input I2C serial clock. 5 V-tolerant input. Requires an external pull-up (≤2 kΩ for a 5 V bus). Supports SCL up to 400 kHz.
9 GND power_in Analog ground. Connect to common supply GND.
10 GND power_in Analog ground. Connect to common supply GND.
11 HPRIGHT output Headphone right channel output. Ground-referenced DirectPath output; connect directly to the right terminal of the headphone jack - no DC blocking capacitor required. Drives loads down to 12.8 Ω (min).
12 VDD power_in Analog VDD supply, 2.5 V to 5.5 V. Must be connected to the common VDD rail. Decouple with its own 1 µF capacitor to analog ground (use pin 13 for the return).
13 GND power_in Analog ground; used to decouple the analog VDD pin (pin 12).
14 HPLEFT output Headphone left channel output. Ground-referenced DirectPath output; connect directly to the left terminal of the headphone jack - no DC blocking capacitor required. Drives loads down to 12.8 Ω (min).
15 CPVSS power_out Negative supply rail generated by the internal charge pump. Decouple to GND (pin 19) or a GND plane with a 1 µF capacitor. Provides the negative rail for the ground-referenced headphone outputs.
16 CPVSS power_out Second CPVSS pin (tied internally with pin 15). Decouple to GND with a 1 µF capacitor.
17 CPN passive Charge-pump flying capacitor negative terminal. Connect one side of the flying capacitor (typically 1 µF) between CPP (pin 18) and CPN.
18 CPP passive Charge-pump flying capacitor positive terminal. Connect one side of the flying capacitor (typically 1 µF) between CPP and CPN (pin 17). Charge-pump switching frequency ≈300-500 kHz.
19 GND power_in Charge-pump ground. Connect to common supply GND. Recommended as the decoupling return for the charge-pump VDD (pin 20).
20 VDD power_in Charge-pump VDD supply, 2.5 V to 5.5 V. Must be tied to the common VDD rail. Decouple to GND (pin 19) with its own 1 µF capacitor.
PAD PAD power_in Exposed thermal pad on the bottom of the WQFN package. Solder to the PCB GND plane for mechanical stability and enhanced thermal performance.
