Texas Instruments · Audio Amplifiers · VQFN-16-EP(3x3)

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).
