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

TPA2012D2RTJR 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 G1 input Gain select MSB. Combined with G0 selects closed-loop voltage gain of 6, 12, 18, or 24 dB. High-level input voltage ≥ 1.3 V; low-level ≤ 0.35 V.
2 OUTL+ output Left channel positive differential Class-D H-bridge output. Drives one side of the left speaker load (typ. 4-8 Ω).
3 PVDD power_in Power supply for the H-bridge output stage (2.5 V to 5.5 V). Must be the same voltage as AVDD. Decouple close to the pin.
4 PGND power_in Power ground return for the H-bridge output stage. Tie to system ground.
5 OUTL- output Left channel negative differential Class-D H-bridge output. Drives the other side of the left speaker load.
6 NC unconnected No internal connection. Leave floating or tie to ground per PCB convenience.
7 SDL input Left channel shutdown terminal, active LOW. Internal 300 kΩ pulldown to enable-by-default-off. Drive high to enable the left channel.
8 SDR input Right channel shutdown terminal, active LOW. Internal 300 kΩ pulldown. Drive high to enable the right channel.
9 AVDD power_in Analog supply input (2.5 V to 5.5 V). Must be the same voltage as PVDD. Decouple close to the pin.
10 NC unconnected No internal connection. Leave floating or tie to ground per PCB convenience.
11 OUTR- output Right channel negative differential Class-D H-bridge output. Drives one side of the right speaker load.
12 PGND power_in Power ground return for the H-bridge output stage. Tie to system ground.
13 PVDD power_in Power supply for the H-bridge output stage (2.5 V to 5.5 V). Must be the same voltage as AVDD.
14 OUTR+ output Right channel positive differential Class-D H-bridge output. Drives the other side of the right speaker load.
15 G0 input Gain select LSB. Combined with G1 sets closed-loop voltage gain (G1,G0 = 00→6 dB, 01→12 dB, 10→18 dB, 11→24 dB).
16 INR+ input Right channel positive audio input. AC-coupled input to the right gain-adjust amplifier.
17 INR- input Right channel negative audio input. AC-coupled input to the right gain-adjust amplifier.
18 AGND power_in Analog ground return. Tie to system ground; keep quiet from switching return currents.
19 INL- input Left channel negative audio input. AC-coupled input to the left gain-adjust amplifier.
20 INL+ input Left channel positive audio input. AC-coupled input to the left gain-adjust amplifier.
21 PAD power_in Exposed thermal PowerPAD on the bottom of the QFN. Must be soldered to PCB GND for electrical ground and thermal dissipation.
