TJM4558CDT

STMicroelectronics · Operational Amplifier · SOIC-8

TJM4558CDT from STMicroelectronics, in a SOIC-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 channel 1. Short-circuit protected (Ios typ. 20 mA). Output resistance ~75 Ω; output swing ±12 V typical with RL=2kΩ at ±15 V supply.
2 IN1- input Inverting input of op-amp channel 1. Input bias current typ. 50 nA; input resistance typ. 2 MΩ; differential input voltage limit ±30 V.
3 IN1+ input Non-inverting input of op-amp channel 1. Common-mode input range ±12 V at ±15 V supply; CMRR typ. 90 dB.
4 VCC- power_in Negative supply rail (VEE). Absolute maximum supply ±22 V; typical operation at ±15 V. May also be tied to GND in single-supply operation.
5 IN2+ input Non-inverting input of op-amp channel 2. Common-mode input range ±12 V at ±15 V supply; CMRR typ. 90 dB.
6 IN2- input Inverting input of op-amp channel 2. Input bias current typ. 50 nA; input resistance typ. 2 MΩ; differential input voltage limit ±30 V.
7 OUT2 output Output of op-amp channel 2. Short-circuit protected (Ios typ. 20 mA). Output resistance ~75 Ω; output swing ±12 V typical with RL=2kΩ at ±15 V supply.
8 VCC+ power_in Positive supply rail. Absolute maximum supply ±22 V; typical operation at ±15 V. Total supply current (both amplifiers, no load) typ. 2.3 mA, max 4.5 mA.

CAD (KiCad official)

  • Symbol: TJM4558CDT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tjm4558cdt-etched.step / tjm4558cdt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tjm4558cdt.step / tjm4558cdt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tjm4558cdt.step 122 KB You want the bare part, or you mark your own boards.
tjm4558cdt-etched.step 2.0 MB You want the part with TJM4558CDT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 495 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: STMicroelectronics datasheet (7 pp, sha256 602f8be3d40dd15d, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
