OPA4347EA 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	Amplifier A output. Rail-to-rail output, swings within 5mV of the supply rails with a 100kΩ load; short-circuit current ±17mA typical.
2	-INA	input	Amplifier A inverting input. Common-mode range extends from (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typical.
3	+INA	input	Amplifier A non-inverting input. Common-mode range extends from (V-)-0.2V to (V+)+0.2V; input bias current ±0.5pA typical.
4	V+	power_in	Positive supply pin. Single-supply operation 2.3V to 5.5V (absolute max V+ − V- = 7.5V). Quiescent current 20µA per amplifier typical.
5	+INB	input	Amplifier B non-inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
6	-INB	input	Amplifier B inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
7	OUTB	output	Amplifier B output. Rail-to-rail output; short-circuit current ±17mA typical.
8	OUTC	output	Amplifier C output. Rail-to-rail output; short-circuit current ±17mA typical.
9	-INC	input	Amplifier C inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
10	+INC	input	Amplifier C non-inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
11	V-	power_in	Negative supply / ground pin. Tie to GND for single-supply operation, or to a negative rail for dual-supply operation. Absolute max V+ − V- = 7.5V.
12	+IND	input	Amplifier D non-inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
13	-IND	input	Amplifier D inverting input. Rail-to-rail input; common-mode range (V-)-0.2V to (V+)+0.2V.
14	OUTD	output	Amplifier D output. Rail-to-rail output; short-circuit current ±17mA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa4347ea.step`	194 KB	You want the bare part, or you mark your own boards.
`opa4347ea-etched.step`	1.9 MB	You want the part with `OPA4347EA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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.
