PAM8301AAF from Diodes Incorporated, in a SOT-23-6. 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 | OUT- | output | Negative (inverted) class-D speaker output; drives the speaker directly with no low-pass filter, per the filterless architecture. |
| 2 | GND | power_in | Ground reference for the device; all voltages in the datasheet are referenced to ground. |
| 3 | IN | input | Audio input; an input coupling capacitor CI is required to bias the signal, with the internal input resistance RI at 10kΩ minimum forming the high-pass corner. |
| 4 | SD | input | Active-low shutdown; a logic low turns the amplifier off, and tying it to GND minimizes idle supply current (SHDN input high 1.2 V min, input low 0.4 V max). |
| 5 | VDD | power_in | Power supply input, rated 2.5 V to 5.5 V; needs local decoupling (about 1.0 µF low-ESR ceramic placed close to VDD plus 10 µF or larger). |
| 6 | OUT+ | output | Positive (non-inverted) class-D speaker output; used differentially with OUT- to drive the load. |
