AD8534ARUZ 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 stage capable of sourcing/sinking up to ±250 mA.
2	-INA	input	Amplifier A inverting input. Rail-to-rail input, common-mode range GND to V+.
3	+INA	input	Amplifier A non-inverting input. Rail-to-rail input, common-mode range GND to V+.
4	V+	power_in	Positive supply rail. Single-supply operation from 2.7 V to 6 V (absolute max 7 V). Bypass with a local decoupling capacitor.
5	+INB	input	Amplifier B non-inverting input. Rail-to-rail input.
6	-INB	input	Amplifier B inverting input. Rail-to-rail input.
7	OUTB	output	Amplifier B output. Rail-to-rail output stage, ±250 mA drive.
8	OUTC	output	Amplifier C output. Rail-to-rail output stage, ±250 mA drive.
9	-INC	input	Amplifier C inverting input. Rail-to-rail input.
10	+INC	input	Amplifier C non-inverting input. Rail-to-rail input.
11	V-	power_in	Negative supply rail. Tie to GND for single-supply operation, or to a negative rail for dual-supply operation.
12	+IND	input	Amplifier D non-inverting input. Rail-to-rail input.
13	-IND	input	Amplifier D inverting input. Rail-to-rail input.
14	OUTD	output	Amplifier D output. Rail-to-rail output stage, ±250 mA drive.

CAD (KiCad official)

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8534aruz.step`	194 KB	You want the bare part, or you mark your own boards.
`ad8534aruz-etched.step`	2.5 MB	You want the part with `AD8534ARUZ` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 622 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.
