RS8034XP from Jiangsu RUNIC Tech, in a SOIC-14. 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	OUT A	output	Amplifier A output. Rail-to-rail output stage; short-circuit current ~11 mA.
2	-IN A	input	Amplifier A inverting input. Rail-to-rail input, common-mode range -0.1 V to Vs+0.1 V (up to 5.6 V at Vs=5.5 V). Input bias current ~1 pA.
3	+IN A	input	Amplifier A non-inverting input. Rail-to-rail input, common-mode range -0.1 V to Vs+0.1 V. Input bias current ~1 pA.
4	V+	power_in	Positive supply rail. Operating range 1.4 V to 5.5 V (7.0 V absolute maximum V+ to V-). Bypass to V- with a local ceramic capacitor.
5	+IN B	input	Amplifier B non-inverting input. Rail-to-rail input, common-mode range -0.1 V to Vs+0.1 V.
6	-IN B	input	Amplifier B inverting input. Rail-to-rail input, input bias current ~1 pA.
7	OUT B	output	Amplifier B output. Rail-to-rail output stage.
8	OUT C	output	Amplifier C output. Rail-to-rail output stage.
9	-IN C	input	Amplifier C inverting input. Rail-to-rail input, input bias current ~1 pA.
10	+IN C	input	Amplifier C non-inverting input. Rail-to-rail input, common-mode range -0.1 V to Vs+0.1 V.
11	V-	power_in	Negative supply rail (ground in single-supply operation). Absolute maximum V+ to V- is 7.0 V.
12	+IN D	input	Amplifier D non-inverting input. Rail-to-rail input, common-mode range -0.1 V to Vs+0.1 V.
13	-IN D	input	Amplifier D inverting input. Rail-to-rail input, input bias current ~1 pA.
14	OUT D	output	Amplifier D output. Rail-to-rail output stage.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`rs8034xp.step`	195 KB	You want the bare part, or you mark your own boards.
`rs8034xp-etched.step`	2.5 MB	You want the part with `RS8034XP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 598 faces against 237 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.
