AS358AMTR-E1 from Diodes Incorporated, in a SOIC-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	OUTPUT1	output	Output of op-amp channel 1. Push-pull output stage capable of sinking and sourcing current; short-circuit protected.
2	-INPUT1	input	Inverting input of op-amp channel 1. High-impedance input; typical input bias current 45 nA.
3	+INPUT1	input	Non-inverting input of op-amp channel 1. Common-mode input range includes ground (V- to V+ - 1.5V).
4	GND	power_in	Negative supply / ground pin (V-). Connect to ground for single-supply operation, or to negative rail for dual-supply operation.
5	+INPUT2	input	Non-inverting input of op-amp channel 2. Common-mode input range includes ground.
6	-INPUT2	input	Inverting input of op-amp channel 2. High-impedance input; typical input bias current 45 nA.
7	OUTPUT2	output	Output of op-amp channel 2. Push-pull output stage capable of sinking and sourcing current; short-circuit protected.
8	VCC	power_in	Positive supply pin (V+). Operating range 3V to 32V single supply, or ±1.5V to ±16V dual supply.

CAD (KiCad official)

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`as358amtr-e1.step`	122 KB	You want the bare part, or you mark your own boards.
`as358amtr-e1-etched.step`	2.3 MB	You want the part with `AS358AMTR-E1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 580 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.
