NCS20072DR2G from ON Semicon ON, 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	OUT1	output	Channel 1 amplifier output. Rail-to-rail output stage; max output current +/-100 mA (absolute max).
2	IN-1	input	Channel 1 inverting input. CMOS high-impedance input; typical input bias current 5 pA. Common-mode range VSS to VDD-1.35 V.
3	IN+1	input	Channel 1 non-inverting input. CMOS high-impedance input; typical input bias current 5 pA. Common-mode range VSS to VDD-1.35 V.
4	VSS	power_in	Negative supply / ground. Total supply range (VDD-VSS) is 2.7 V to 36 V (single supply) or +/-1.35 V to +/-18 V (split supply).
5	IN+2	input	Channel 2 non-inverting input. CMOS high-impedance input; typical input bias current 5 pA. Common-mode range VSS to VDD-1.35 V.
6	IN-2	input	Channel 2 inverting input. CMOS high-impedance input; typical input bias current 5 pA. Common-mode range VSS to VDD-1.35 V.
7	OUT2	output	Channel 2 amplifier output. Rail-to-rail output stage; max output current +/-100 mA (absolute max).
8	VDD	power_in	Positive supply. Operating range 2.7 V to 36 V (single supply) with respect to VSS. Absolute max supply voltage 40 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ncs20072dr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`ncs20072dr2g-etched.step`	2.7 MB	You want the part with `NCS20072DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 643 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.
