LF353DR from Texas Instruments, 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	1OUT	output	Output of op-amp 1. Maximum peak output voltage swing ±13.5 V typ into RL = 10 kΩ (VCC±=±15 V).
2	1IN-	input	Inverting input of op-amp 1. JFET input, input bias current 50 pA typ, input impedance ~10^12 Ω.
3	1IN+	input	Noninverting input of op-amp 1. JFET input, input bias current 50 pA typ, common-mode input range VCC- +4 V to VCC+ -4 V.
4	VCC-	power_in	Negative supply voltage. Recommended -3.5 V to -18 V; absolute max -18 V. Shared between both op-amps.
5	2IN+	input	Noninverting input of op-amp 2. JFET input, input bias current 50 pA typ, common-mode input range VCC- +4 V to VCC+ -4 V.
6	2IN-	input	Inverting input of op-amp 2. JFET input, input bias current 50 pA typ, input impedance ~10^12 Ω.
7	2OUT	output	Output of op-amp 2. Maximum peak output voltage swing ±13.5 V typ into RL = 10 kΩ (VCC±=±15 V).
8	VCC+	power_in	Positive supply voltage. Recommended 3.5 V to 18 V; absolute max 18 V. Supply current 3.6 mA typ. Shared between both op-amps.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lf353dr.step`	122 KB	You want the bare part, or you mark your own boards.
`lf353dr-etched.step`	1.7 MB	You want the part with `LF353DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 420 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.
