OPA314AIDCKR from Texas Instruments, in a SC-70-5. 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	+IN	input	Noninverting input of the op-amp. Rail-to-rail input stage with very low bias current (0.2pA typical).
2	V-	power_in	Negative (lowest) supply. Ground for single-supply operation, or negative rail for dual-supply operation. Supply range 1.8V to 5.5V total (V+ − V−).
3	-IN	input	Inverting input of the op-amp. Rail-to-rail input stage with very low bias current (0.2pA typical).
4	OUT	output	Rail-to-rail output of the op-amp. Drives loads to within millivolts of either supply rail.
5	V+	power_in	Positive (highest) supply. 1.8V to 5.5V single supply, or up to ±2.75V dual supply. Bypass to V− with a 0.1µF ceramic capacitor close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa314aidckr.step`	87 KB	You want the bare part, or you mark your own boards.
`opa314aidckr-etched.step`	2.0 MB	You want the part with `OPA314AIDCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 509 faces against 102 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.
