TL972IDR 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	OUT1	output	Op-amp channel 1 output. Rail-to-rail output stage swings to within ~100 mV of the supply rails under light load.
2	IN1-	input	Inverting input of op-amp channel 1. Differential input voltage limited to ±1 V absolute maximum with respect to the non-inverting input.
3	IN1+	input	Non-inverting input of op-amp channel 1. Common-mode input range is Vcc-+1.15 V to Vcc+-1.15 V.
4	VCC-	power_in	Negative supply rail. Connect to GND for single-supply operation, or to the negative rail for split-supply operation. Total supply range Vcc+ - Vcc- = 2.7 V to 12 V (15 V abs max).
5	IN2+	input	Non-inverting input of op-amp channel 2. Common-mode input range is Vcc-+1.15 V to Vcc+-1.15 V.
6	IN2-	input	Inverting input of op-amp channel 2. Differential input voltage limited to ±1 V absolute maximum with respect to the non-inverting input.
7	OUT2	output	Op-amp channel 2 output. Rail-to-rail output stage swings to within ~100 mV of the supply rails under light load.
8	VCC+	power_in	Positive supply rail. Connect to the positive supply (single- or split-supply). Total supply range Vcc+ - Vcc- = 2.7 V to 12 V (15 V abs max). Bypass with a 0.1 µF ceramic close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tl972idr.step`	122 KB	You want the bare part, or you mark your own boards.
`tl972idr-etched.step`	1.5 MB	You want the part with `TL972IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 390 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.
