AD8002D 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. High-level places the chip in shutdown/sleep mode (leakage ~18µA typ); low-level enables normal operation. Has an internal pull-up per the typical application diagram.
2	BYP	passive	Internal common-mode voltage (VDD/2) bypass. Connect a 1µF capacitor from this pin to GND to filter the mid-rail bias reference.
3	+IN	input	Non-inverting analog audio input to the internal input amplifier.
4	-IN	input	Inverting analog audio input. Gain is set by an external input resistor (e.g. 22kΩ) and feedback resistor (e.g. 68kΩ) as shown in the typical application.
5	VO1	output	Bridge-tied load audio output 1. Connect one terminal of the speaker between VO1 (pin 5) and VO2 (pin 8). No output coupling capacitor required.
6	VCC	power_in	Positive supply voltage input, 2.2V to 5.5V operating range. Bypass locally with a 1µF (and typically an additional bulk) capacitor to GND.
7	GND	power_in	Power ground return for supply and audio output stage.
8	VO2	output	Bridge-tied load audio output 2. Complementary to VO1; the speaker connects across VO1 and VO2 for full BTL drive.

AD8002D

CAD (KiCad official)

Symbol: AD8002D
Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8002d.step`	122 KB	You want the bare part, or you mark your own boards.
`ad8002d-etched.step`	1.8 MB	You want the part with `AD8002D` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 445 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.
