OPA1652AIDR 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	Channel A amplifier output. Rail-to-rail output stage, swings to within 800 mV of the supply rails with a 2 kΩ load; short-circuit current ±50 mA.
2	-IN A	input	Channel A inverting input. FET input, typical bias current 10 pA. Common-mode range (V−)+0.5 V to (V+)−2 V.
3	+IN A	input	Channel A non-inverting input. FET input, typical bias current 10 pA. Common-mode range (V−)+0.5 V to (V+)−2 V.
4	V-	power_in	Negative supply rail. Use −(VS/2) for split supplies or GND for single-supply operation. Total supply (V+)−(V−) range 4.5 V to 36 V (abs. max 40 V).
5	+IN B	input	Channel B non-inverting input. FET input, typical bias current 10 pA. Common-mode range (V−)+0.5 V to (V+)−2 V.
6	-IN B	input	Channel B inverting input. FET input, typical bias current 10 pA. Common-mode range (V−)+0.5 V to (V+)−2 V.
7	OUT B	output	Channel B amplifier output. Rail-to-rail output stage, swings to within 800 mV of the supply rails with a 2 kΩ load; short-circuit current ±50 mA.
8	V+	power_in	Positive supply rail. Total supply (V+)−(V−) range 4.5 V to 36 V (abs. max 40 V). Bypass with a local decoupling capacitor to V−.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa1652aidr.step`	122 KB	You want the bare part, or you mark your own boards.
`opa1652aidr-etched.step`	2.1 MB	You want the part with `OPA1652AIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 535 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.
