JRC4558D

UMW · Operational Amplifier · SOP-8

JRC4558D from UMW, 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 OUT1 output Output of op-amp A. Drives loads down to 2 kΩ with ±13 V typical output swing on ±15 V supplies; short-circuit current 40-80 mA.
2 IN1- input Inverting input of op-amp A. Typical input bias current 25 nA, input offset voltage 2 mV (Rs < 10 kΩ).
3 IN1+ input Non-inverting (in-phase) input of op-amp A. Common-mode input voltage range typically ±14 V on ±15 V supplies.
4 VEE power_in Negative supply rail. Rated to −18 V max; typical operation at −15 V. Supply current 3.5 mA typical (both amplifiers).
5 IN2+ input Non-inverting (in-phase) input of op-amp B. Common-mode input voltage range typically ±14 V on ±15 V supplies.
6 IN2- input Inverting input of op-amp B. Typical input bias current 25 nA, input offset voltage 2 mV (Rs < 10 kΩ).
7 OUT2 output Output of op-amp B. Drives loads down to 2 kΩ with ±13 V typical output swing on ±15 V supplies; short-circuit current 40-80 mA.
8 VCC power_in Positive supply rail. Rated to +18 V max; typical operation at +15 V. Bypass to VEE with a local decoupling capacitor.

Ordering variants

Same part, different packaging or reel option.

  • JRC4558D

CAD (KiCad official)

  • Symbol: JRC4558D
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: jrc4558d-etched.step / jrc4558d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jrc4558d.step / jrc4558d.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
jrc4558d.step 122 KB You want the bare part, or you mark your own boards.
jrc4558d-etched.step 2.0 MB You want the part with JRC4558D already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 478 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: UMW datasheet (9 pp, sha256 fea0f3600e8f1c74, retrieved 2026-08-17, tier: lcsc)
  • 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).
