PAM8302AASCR from Diodes Incorporated, in a MSOP-8. 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	SD	input	Active-low shutdown input. Drive low (<0.4V) to place amplifier in low-current shutdown; drive high (>1.2V, up to VDD) for normal operation. Also serves as UVLO recovery pin (supply must recover above ~2.1V and SD toggled).
2	NC	unconnected	No internal connection. Leave floating or tie to ground for board-layout convenience.
3	IN+	input	Non-inverting audio input. AC-coupled through CI (0.1µF-0.22µF typical) forming a high-pass filter with the internal 10k input resistor. Internal bias holds input at VDD/2.
4	IN-	input	Inverting audio input. AC-coupled through CI (0.1µF-0.22µF typical); paired with IN+ for differential drive or tied through CI to ground for single-ended input. Internal 10k input resistor, 150k feedback resistor (Av = 20·log(150k/10k) ≈ 23.5dB).
5	VO+	output	Positive Class-D BTL output. Connects directly to one speaker terminal (filterless) or through a ferrite-bead EMI filter (typ ferrite + 220pF to GND). Drives 4Ω or 8Ω loads; up to 2.5W at 5V into 4Ω (THD+N=10%).
6	VDD	power_in	Positive supply input, 2.0V to 5.5V (absolute max 6.0V). Decouple with 1µF ceramic close to pin plus a bulk 10µF (larger recommended for EMI/low-frequency response). Quiescent current typ 4mA; shutdown current typ <1µA.
7	GND	power_in	Device ground / return for supply and audio signals. All voltages are referenced to this pin.
8	VO-	output	Negative Class-D BTL output. Connects to the other speaker terminal (filterless) or through a ferrite-bead EMI filter (typ ferrite + 220pF to GND). Complementary to VO+ in bridge-tied-load configuration.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`pam8302aascr.step`	123 KB	You want the bare part, or you mark your own boards.
`pam8302aascr-etched.step`	2.7 MB	You want the part with `PAM8302AASCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 652 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
