OPA4348AIPWR from UMW, in a TSSOP-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	OUTA	output	Op-amp A output. Rail-to-rail output; short-circuit current typ. ±10mA.
2	-INA	input	Op-amp A inverting input. Rail-to-rail input; input bias typ. 0.5pA.
3	+INA	input	Op-amp A non-inverting input. Rail-to-rail input; input bias typ. 0.5pA.
4	V+	power_in	Positive supply rail. Single-supply +2.1V to +5.5V (7.5V abs. max). Bypass with 0.1µF to V-.
5	+INB	input	Op-amp B non-inverting input. Rail-to-rail input.
6	-INB	input	Op-amp B inverting input. Rail-to-rail input.
7	OUTB	output	Op-amp B output. Rail-to-rail output.
8	OUTC	output	Op-amp C output. Rail-to-rail output.
9	-INC	input	Op-amp C inverting input. Rail-to-rail input.
10	+INC	input	Op-amp C non-inverting input. Rail-to-rail input.
11	V-	power_in	Negative supply rail (ground in single-supply operation). Referenced to V+ for the 2.1V-5.5V total supply range.
12	+IND	input	Op-amp D non-inverting input. Rail-to-rail input.
13	-IND	input	Op-amp D inverting input. Rail-to-rail input.
14	OUTD	output	Op-amp D output. Rail-to-rail output.

CAD (KiCad official)

Symbol: OPA4348AIPWR
Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa4348aipwr.step`	194 KB	You want the bare part, or you mark your own boards.
`opa4348aipwr-etched.step`	2.6 MB	You want the part with `OPA4348AIPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 669 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.
