OP07CP from Texas Instruments, in a PDIP-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	OFFSET N1	passive	Offset null terminal 1. Connect a 20 kΩ potentiometer between OFFSET N1 (pin 1) and OFFSET N2 (pin 8) with the wiper tied to VCC+ to null the input offset voltage. Offset adjustment range is ±4 mV typ with Rs = 20 kΩ.
2	IN-	input	Inverting input of the op-amp. Common-mode input voltage range ±13 V (typ ±14 V) at VCC± = ±15 V; input bias current ±1.8 nA typ; input resistance 33 MΩ typ. Differential input voltage must not exceed ±30 V.
3	IN+	input	Non-inverting input of the op-amp. Common-mode input voltage range ±13 V (typ ±14 V) at VCC± = ±15 V; input bias current ±1.8 nA typ; input resistance 33 MΩ typ.
4	VCC-	power_in	Negative supply rail. Recommended operating range −3 V to −18 V; absolute maximum −22 V. Together with VCC+ powers the op-amp; total supply typically ±15 V for characterization.
5	NC	unconnected	No internal connection. Leave floating or tie to a convenient node; not bonded to the die.
6	OUT	output	Op-amp output. Peak output voltage ±13 V typ (RL ≥ 10 kΩ) at VCC± = ±15 V; large-signal voltage amplification 400 V/mV typ; slew rate 0.3 V/µs; unity-gain bandwidth 0.6 MHz typ. Short-circuit to ground or either supply is permitted indefinitely.
7	VCC+	power_in	Positive supply rail. Recommended operating range +3 V to +18 V; absolute maximum +22 V. Also serves as the wiper reference for the external 20 kΩ offset-null potentiometer.
8	OFFSET N2	passive	Offset null terminal 2. Connect a 20 kΩ potentiometer between OFFSET N1 (pin 1) and OFFSET N2 (pin 8) with the wiper tied to VCC+ to null the input offset voltage.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`op07cp.step`	271 KB	You want the bare part, or you mark your own boards.
`op07cp-etched.step`	1.4 MB	You want the part with `OP07CP` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 348 faces against 148 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.
