LM2904DMR2G

onsemi · Operational Amplifier · MSOP-8

LM2904DMR2G from onsemi, 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 OUTA output Output of op-amp A. Push-pull output, short-circuit protected; typical short-circuit current 40 mA. Output voltage swings from near VEE/Gnd up to VCC - ~1.5 V.
2 INA- input Inverting input of op-amp A. High impedance differential input; input bias current typ -45 nA. Common-mode range 0 V to VCC - 1.7 V.
3 INA+ input Non-inverting input of op-amp A. High impedance differential input; input bias current typ -45 nA. Common-mode range extends to VEE/Gnd (0 V).
4 VEE/GND power_in Negative supply / ground. Connect to 0 V in single-supply operation, or to negative rail (down to -16 V) in split-supply operation.
5 INB+ input Non-inverting input of op-amp B. High impedance differential input; input bias current typ -45 nA. Common-mode range extends to VEE/Gnd (0 V).
6 INB- input Inverting input of op-amp B. High impedance differential input; input bias current typ -45 nA. Common-mode range 0 V to VCC - 1.7 V.
7 OUTB output Output of op-amp B. Push-pull output, short-circuit protected; typical short-circuit current 40 mA. Output voltage swings from near VEE/Gnd up to VCC - ~1.5 V.
8 VCC power_in Positive supply. 3.0 V to 32 V single-supply, or up to +16 V split-supply. Total device quiescent current typ 0.7 mA at VCC = 5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm2904dmr2g.step 123 KB You want the bare part, or you mark your own boards.
lm2904dmr2g-etched.step 2.3 MB You want the part with LM2904DMR2G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 564 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: onsemi datasheet (14 pp, sha256 3a1bc4722a28615c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
