PAM8403DR-H

Diodes Incorporated · Audio Power OpAmps · SOIC-16

PAM8403DR-H 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 Class-D bridge output. Drives one terminal of the left speaker directly (filterless BTL output).
2 PGND power_in Power ground return for the left-channel Class-D output stage. Should be tied to the system ground plane with low-impedance routing.
3 -OUT_L output Left channel negative Class-D bridge output. Drives the opposite terminal of the left speaker (BTL pair with +OUT_L).
4 PVDD power_in Power supply input for the left-channel Class-D output stage. 2.5V to 5.5V, absolute max 6.0V. Bypass locally with a bulk capacitor (typ. 470 uF) and a 0.1 uF ceramic.
5 MUTE input Mute control input, active low. Drive high (VIH >= 1.5V) for normal operation; drive low (VIL <= 0.4V) to mute both channels. Muting current typ. 3.5 mA when VMUTE = 0.3V.
6 VDD power_in Analog supply input for the internal signal-path circuitry. 2.5V to 5.5V, tied to the same rail as PVDD in typical applications; bypass with a 1 uF ceramic to GND.
7 INL input Left-channel single-ended analog audio input. AC-coupled through an input capacitor (typ. 0.47 uF) from the source. Closed-loop gain is typ. 24 dB.
8 VREF passive Internal analog reference (mid-supply bias). Connect a bypass capacitor (typ. 0.1 uF-1 uF) from this pin to GND; do not load externally.
9 NC unconnected No connect. Leave floating or tie to GND for mechanical support; do not use for signal routing.
10 INR input Right-channel single-ended analog audio input. AC-coupled through an input capacitor (typ. 0.47 uF) from the source. Closed-loop gain is typ. 24 dB.
11 GND power_in Analog ground reference for the signal-path circuitry. Connect to the system ground plane; keep separate from the PGND return path back to the star point.
12 SHDN input Shutdown control input, active low. Drive high (VIH >= 1.5V) to enable the device; drive low (VIL <= 0.4V) to enter shutdown (ISD < 1 uA typ.).
13 PVDD power_in Power supply input for the right-channel Class-D output stage. 2.5V to 5.5V, absolute max 6.0V. Bypass locally with a bulk capacitor (typ. 470 uF) and a 0.1 uF ceramic.
14 -OUT_R output Right channel negative Class-D bridge output. Drives one terminal of the right speaker directly (filterless BTL output).
15 PGND power_in Power ground return for the right-channel Class-D output stage. Should be tied to the system ground plane with low-impedance routing.
16 +OUT_R output Right channel positive Class-D bridge output. Drives the opposite terminal of the right speaker (BTL pair with -OUT_R).
