LM741M

HGSEMI · Operational Amplifier · SOP-8

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.

CAD (KiCad official)

  • Symbol: LM741M
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm741m-etched.step / lm741m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm741m.step / lm741m.glb are the bare package body.

3D model downloads

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HGSEMI datasheet (9 pp, sha256 2c15bc22a02b633a, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
