LT1013DDR 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	1IN+	input	Noninverting input for channel 1 (amplifier A). Common-mode range extends to VCC- and up to VCC+ - 2 V.
2	VCC-	power_in	Negative supply voltage. Connect to ground for single-supply operation, or to a negative rail for dual-supply (e.g. -15 V). Total supply (VCC+ - VCC-) is 5 V to 44 V max.
3	2IN+	input	Noninverting input for channel 2 (amplifier B). Common-mode range extends to VCC- and up to VCC+ - 2 V.
4	2IN-	input	Inverting input for channel 2 (amplifier B). Differential input voltage limited to ±30 V absolute maximum.
5	2OUT	output	Output for channel 2 (amplifier B). Swings to within a few millivolts of ground while sinking current; short-circuit protected to either supply.
6	VCC+	power_in	Positive supply voltage. Range from 5 V (single supply) up to +15 V dual-supply; VCC+ - VCC- must not exceed 44 V.
7	1OUT	output	Output for channel 1 (amplifier A). Swings to within a few millivolts of ground while sinking current; short-circuit protected to either supply.
8	1IN-	input	Inverting input for channel 1 (amplifier A). Differential input voltage limited to ±30 V absolute maximum.

CAD (KiCad official)

3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lt1013ddr.step`	122 KB	You want the bare part, or you mark your own boards.
`lt1013ddr-etched.step`	1.7 MB	You want the part with `LT1013DDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 445 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.
