AD8534ARZ from UMW, in a SOP-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	Output of amplifier A. Rail-to-rail output capable of sourcing/sinking up to +/-250 mA.
2	-INA	input	Inverting input of amplifier A. Rail-to-rail input, input voltage range 0 V to Vs.
3	+INA	input	Non-inverting input of amplifier A. Rail-to-rail input, input voltage range 0 V to Vs.
4	V+	power_in	Positive supply voltage. Single-supply range 2.7 V to 6 V; absolute maximum 7 V. Shared by all four amplifiers.
5	+INB	input	Non-inverting input of amplifier B. Rail-to-rail input, input voltage range 0 V to Vs.
6	-INB	input	Inverting input of amplifier B. Rail-to-rail input, input voltage range 0 V to Vs.
7	OUTB	output	Output of amplifier B. Rail-to-rail output capable of sourcing/sinking up to +/-250 mA.
8	OUTC	output	Output of amplifier C. Rail-to-rail output capable of sourcing/sinking up to +/-250 mA.
9	-INC	input	Inverting input of amplifier C. Rail-to-rail input, input voltage range 0 V to Vs.
10	+INC	input	Non-inverting input of amplifier C. Rail-to-rail input, input voltage range 0 V to Vs.
11	V-	power_in	Negative supply / ground. In single-supply operation, tie to GND. Shared by all four amplifiers.
12	+IND	input	Non-inverting input of amplifier D. Rail-to-rail input, input voltage range 0 V to Vs.
13	-IND	input	Inverting input of amplifier D. Rail-to-rail input, input voltage range 0 V to Vs.
14	OUTD	output	Output of amplifier D. Rail-to-rail output capable of sourcing/sinking up to +/-250 mA.

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

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ad8534arz.step`	195 KB	You want the bare part, or you mark your own boards.
`ad8534arz-etched.step`	2.3 MB	You want the part with `AD8534ARZ` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 575 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.
