JRC4558DTR from XBLW, 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 operational amplifier 1. Large-signal swing typically ±14 V with RL > 10 kΩ at ±15 V supplies; slew rate 1.5 V/µs.
2	IN1(-)	input	Inverting (negative) input of operational amplifier 1. Typical input bias current 30 nA, input offset voltage 2 mV; differential input voltage rated up to ±18 V.
3	IN1(+)	input	Non-inverting (positive) input of operational amplifier 1. Common-mode input voltage range typically ±12 V at ±15 V supplies; input pin voltage rated ±15 V.
4	Vee	power_in	Negative supply / ground. Operating supply range ±4 V to ±18 V (single-supply or dual-supply). Absolute max Vcc/Vee = ±18 V.
5	IN2(+)	input	Non-inverting (positive) input of operational amplifier 2. Common-mode input voltage range typically ±12 V at ±15 V supplies.
6	IN2(-)	input	Inverting (negative) input of operational amplifier 2. Typical input bias current 30 nA, input offset voltage 2 mV.
7	OUT2	output	Output of operational amplifier 2. Output swing 0 to (Vcc - 1.5 V); slew rate 1.5 V/µs; drives loads down to 2 kΩ.
8	Vcc	power_in	Positive power supply. Operating range ±4 V to ±18 V (or 8 V to 36 V single supply). Typical supply current 3.5 mA (5.7 mA max) for both amplifiers.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`jrc4558dtr.step`	122 KB	You want the bare part, or you mark your own boards.
`jrc4558dtr-etched.step`	2.2 MB	You want the part with `JRC4558DTR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 547 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.
