AD8002B from IDCHIP, in a SOP-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	Shutdown control input. Logic HIGH puts the chip into low-power shutdown (typ. 25µA); logic LOW enables normal operation. At 5V supply the shutdown threshold is ~1.6V and enable threshold is ~1.2V. Has an internal pull-up.
2	BYP	passive	Bypass pin for the internal VDD/2 mid-supply reference. Connect a 1µF capacitor from BYP to GND to filter the internal common-mode reference voltage and reduce power-supply noise coupling into the amplifier.
3	+IN	input	Non-inverting analog audio input to the internal op-amp. Typically AC-coupled to signal ground through an input capacitor in single-ended input applications.
4	-IN	input	Inverting analog audio input. Audio source is AC-coupled here (typ. 0.22µF) through a series input resistor (typ. 22kΩ); a feedback resistor (typ. 68kΩ) from VO1 sets the closed-loop gain (Av = -Rf/Rin).
5	VO1	output	BTL audio output 1 (VO-). One side of the bridge-tied speaker load; connects directly to one speaker terminal with no output coupling capacitor required. Drives up to 3W into a 4Ω load (BTL) at 5V.
6	VDD	power_in	Positive supply voltage input. Operating range 2V to 6.5V; typical 5V. Decouple with a 1µF (or larger) ceramic capacitor to GND close to the pin.
7	GND	power_in	Device ground / power return. Connect to the system analog ground plane.
8	VO2	output	BTL audio output 2 (VO+). The complementary side of the bridge-tied speaker load; drives the other speaker terminal 180° out of phase with VO1. No output DC-blocking capacitor required.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8002b.step`	122 KB	You want the bare part, or you mark your own boards.
`ad8002b-etched.step`	1.9 MB	You want the part with `AD8002B` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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.
