PAM8406DR

Diodes Incorporated · Audio Power OpAmps · SOIC-16

PAM8406DR from Diodes Incorporated, in a SOIC-16. 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 +OUT_L output Left channel positive (non-inverting) speaker output from the BTL power stage. Drives one terminal of the left speaker load (2Ω/4Ω/8Ω) in Class-D or Class-AB mode.
2 PGNDL power_in Power ground return for the left channel Class-D/AB output stage. Should be tied to the main system ground plane with low-impedance routing.
3 -OUT_L output Left channel negative (inverting) speaker output from the BTL power stage. Second terminal of the left speaker load, differential with +OUT_L.
4 PVDDL power_in Power supply input for the left channel output stage (2.5V-5.5V). Bypass locally with ceramic capacitors close to the pin.
5 MUTE input Active-low mute control input. Drive low to mute both channels; drive high (VIH ≥ 1.4V) for normal operation. VIL ≤ 0.4V at VDD = 5.0V.
6 VDD power_in Analog VDD supply for the internal small-signal circuitry (2.5V-5.5V). Bypass to GND with a low-ESR ceramic capacitor.
7 INL input Left channel single-ended audio input. AC-coupled through an external input capacitor to set the high-pass corner; internally biased to VDD/2.
8 VREF passive Internal analog reference (mid-supply bias) output. Connect a bypass capacitor from VREF to GND for PSRR and low-noise operation.
9 MODE input Output mode select. Logic high (≥1.4V) selects Class-D filterless output; logic low (≤0.4V) selects Class-AB output.
10 INR input Right channel single-ended audio input. AC-coupled through an external input capacitor to set the high-pass corner; internally biased to VDD/2.
11 GND power_in Analog ground return for the small-signal front end and reference circuitry. Tie to the system ground plane.
12 SHDN input Active-low shutdown control. Drive low to place the device in low-current shutdown (ISD < 1µA); drive high (≥1.4V) to enable. VIL ≤ 0.4V at VDD = 5.0V.
13 PVDDR power_in Power supply input for the right channel output stage (2.5V-5.5V). Bypass locally with ceramic capacitors close to the pin.
14 -OUT_R output Right channel negative (inverting) speaker output from the BTL power stage. Second terminal of the right speaker load, differential with +OUT_R.
15 PGNDR power_in Power ground return for the right channel Class-D/AB output stage. Tie to the main system ground plane with low-impedance routing.
16 +OUT_R output Right channel positive (non-inverting) speaker output from the BTL power stage. Drives one terminal of the right speaker load (2Ω/4Ω/8Ω) in Class-D or Class-AB mode.
