AMC1301DWVR from Texas Instruments, in a SOIC-8-300mil. 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	VDD1	power_in	High-side power supply, 3.0 V to 5.5 V (nominal 5.0 V). Decouple to GND1 per Power Supply Recommendations section.
2	VINP	input	Noninverting analog input. Part of the ±250-mV differential input pair connected across the shunt resistor; input voltage range GND1 to VDD1+0.5 V (absolute max), specified ±250 mV differential.
3	VINN	input	Inverting analog input. Part of the ±250-mV differential input pair connected across the shunt resistor; input voltage range GND1 to VDD1+0.5 V (absolute max).
4	GND1	power_in	High-side analog ground reference for VDD1, VINP, and VINN.
5	GND2	power_in	Low-side analog ground reference for VDD2, VOUTP, and VOUTN.
6	VOUTN	output	Inverting analog output. Part of the differential output pair (VOUTP/VOUTN) with fixed gain of 8.2 relative to the input; referenced to GND2/VDD2 on the low-side.
7	VOUTP	output	Noninverting analog output. Part of the differential output pair (VOUTP/VOUTN) with fixed gain of 8.2 relative to the input; referenced to GND2/VDD2 on the low-side.
8	VDD2	power_in	Low-side power supply, 3.0 V to 5.5 V (nominal 3.3 V or 5.0 V). Decouple to GND2 per Power Supply Recommendations section.

CAD (KiCad official)

Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOIC-8-300mil (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`amc1301dwvr.step`	122 KB	You want the bare part, or you mark your own boards.
`amc1301dwvr-etched.step`	2.0 MB	You want the part with `AMC1301DWVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 519 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.
