OPA2197IDR from Texas Instruments, in a SOIC-8. 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	Output of amplifier channel A. Rail-to-rail output stage capable of sourcing/sinking up to ±65 mA and driving up to 1 nF capacitive load.
2	-IN A	input	Inverting input of amplifier channel A. Rail-to-rail input range extending 100 mV beyond each supply; low input bias current (±5 pA typical).
3	+IN A	input	Non-inverting input of amplifier channel A. Rail-to-rail input range with EMI/RFI filtering; supports differential input voltage to the supply rail.
4	V-	power_in	Negative (lowest) power supply. Operates with dual supplies of ±2.25 V to ±18 V or single supply of 4.5 V to 36 V (referenced to V+). Quiescent current ~1 mA per amplifier.
5	+IN B	input	Non-inverting input of amplifier channel B. Rail-to-rail input range with EMI/RFI filtering; supports differential input voltage to the supply rail.
6	-IN B	input	Inverting input of amplifier channel B. Rail-to-rail input range extending 100 mV beyond each supply; low input bias current (±5 pA typical).
7	OUT B	output	Output of amplifier channel B. Rail-to-rail output stage capable of sourcing/sinking up to ±65 mA and driving up to 1 nF capacitive load.
8	V+	power_in	Positive (highest) power supply. Operates with dual supplies of ±2.25 V to ±18 V or single supply of 4.5 V to 36 V. Absolute maximum supply span is 40 V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa2197idr.step`	122 KB	You want the bare part, or you mark your own boards.
`opa2197idr-etched.step`	1.9 MB	You want the part with `OPA2197IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 479 faces against 147 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.
