LM741M from HGSEMI, in a SOP-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_NULL	passive	Offset null pin. Used together with pin 5 and a 10 kΩ potentiometer (wiper tied to V-) to trim the input offset voltage of the op-amp to zero.
2	IN-	input	Inverting input of the operational amplifier. Differential input voltage rating ±30V; input voltage range typ ±13V at Vs=±15V. Typical input bias current 80 nA, input resistance ~2 MΩ.
3	IN+	input	Non-inverting input of the operational amplifier. Differential input voltage rating ±30V; input voltage range typ ±13V at Vs=±15V. Typical input bias current 80 nA, input resistance ~2 MΩ.
4	V-	power_in	Negative supply rail. Absolute maximum ±18V (total supply). Together with V+ powers the op-amp; typical supply current 1.7 mA.
5	OFFSET_NULL	passive	Offset null pin. Used together with pin 1 and a 10 kΩ potentiometer (wiper tied to V-) to trim the input offset voltage of the op-amp to zero.
6	OUT	output	Amplifier output. Class-AB output stage with continuous short-circuit protection (25 mA typical short-circuit current). Output swing ±14V typ at Vs=±15V with RL≥10kΩ.
7	V+	power_in	Positive supply rail. Absolute maximum ±18V (total supply). Typical power consumption 50 mW at Vs=±15V.
8	NC	unconnected	No internal connection. Leave floating or tie to any convenient potential; not used by the die.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm741m.step`	122 KB	You want the bare part, or you mark your own boards.
`lm741m-etched.step`	998 KB	You want the part with `LM741M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 278 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.
