LM2904MM

HGSEMI · Operational Amplifier · MSOP-8

LM2904MM from HGSEMI, in a MSOP-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 1OUT output Op-amp 1 output. Class-AB output stage with internal short-circuit protection; typical short-circuit current ±24 mA. VOH ≈ VCC-1.5 V, VOL near VEE.
2 1IN- input Op-amp 1 inverting input. Typical input bias current 50 nA, input offset current 10 nA. Differential input voltage rating ±36 V.
3 1IN+ input Op-amp 1 non-inverting input. Common-mode input voltage range extends from VEE to VCC-1.5 V (single-supply rail-to-rail on the negative rail).
4 VEE power_in Negative supply (or GND for single-supply operation). Range: 0 V (single-supply) or down to -18 V (dual-supply).
5 2IN+ input Op-amp 2 non-inverting input. Common-mode input voltage range extends from VEE to VCC-1.5 V.
6 2IN- input Op-amp 2 inverting input. Typical input bias current 50 nA, input offset current 10 nA. Differential input voltage rating ±36 V.
7 2OUT output Op-amp 2 output. Class-AB output stage with internal short-circuit protection; typical short-circuit current ±24 mA.
8 VCC power_in Positive supply. Single-supply range 3 V to 36 V; dual-supply up to +18 V. Typical quiescent current 0.5 mA at VCC=5 V, 0.8 mA at VCC=36 V.

CAD (KiCad official)

  • Symbol: LM2904MM
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm2904mm-etched.step / lm2904mm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm2904mm.step / lm2904mm.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2904mm.step 123 KB You want the bare part, or you mark your own boards.
lm2904mm-etched.step 1.6 MB You want the part with LM2904MM already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 419 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
