TPA4411MRTJR

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

TPA4411MRTJR 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 C1P passive Charge pump flying capacitor positive terminal.
2 PGND power_in Power ground, connect to ground.
3 C1N passive Charge pump flying capacitor negative terminal.
4 NC unconnected No connection.
5 PVSS power_out Output from charge pump (negative supply rail).
6 NC unconnected No connection.
7 SVSS power_in Amplifier negative supply, connect to PVSS via star connection.
8 NC unconnected No connection.
9 OUTL output Left audio channel output signal.
10 SVDD power_in Amplifier positive supply, connect to PVDD via star connection.
11 OUTR output Right audio channel output signal.
12 NC unconnected No connection.
13 INL input Left audio channel input signal.
14 SDR input Right channel shutdown, active low logic (VIH min 1.5 V, VIL max 0.5 V).
15 INR input Right audio channel input signal.
16 NC unconnected No connection.
17 SGND power_in Signal ground, connect to ground; route separately from PGND back to the decoupling capacitor.
18 SDL input Left channel shutdown, active low logic (VIH min 1.5 V, VIL max 0.5 V).
19 PVDD power_in Supply voltage, connect to positive supply (1.8 V to 4.5 V).
20 NC unconnected No connection.
21 EP passive Exposed pad must be soldered to a floating PCB plane; do not connect to power or ground since it is connected internally to PVSS.
