PAM8407DR from Diodes Incorporated, in a SOIC-16. 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 | RINP | input | Positive input of the right channel power amplifier. |
| 2 | RINN | input | Negative input of the right channel power amplifier. |
| 3 | SD | input | Full chip shutdown control input, active low; the SD pin cannot be left floating due to the internal pull-down. |
| 4 | UP | input | Volume UP control, active low; trigger points are 70% of VDD minimum for logic high and 20% of VDD maximum for logic low. |
| 5 | DOWN | input | Volume DOWN control, active low; trigger points are 70% of VDD minimum for logic high and 20% of VDD maximum for logic low. |
| 6 | GND | power_in | Ground. |
| 7 | LINN | input | Negative input of the left channel power amplifier. |
| 8 | LINP | input | Positive input of the left channel power amplifier. |
| 9 | VDD | power_in | Power supply, 2.5 V to 6.0 V operating range. |
| 10 | LOUTP | output | Positive output of the left channel power amplifier. |
| 11 | LOUTN | output | Negative output of the left channel power amplifier. |
| 12 | GND | power_in | Ground. |
| 13 | GND | power_in | Ground. |
| 14 | ROUTN | output | Negative output of the right channel power amplifier. |
| 15 | ROUTP | output | Positive output of the right channel power amplifier. |
| 16 | VDD | power_in | Power supply, 2.5 V to 6.0 V operating range. |
