TLC2272IDR 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 amplifier Channel 1. Rail-to-rail output stage capable of ±50 mA output current.
2	1IN-	input	Inverting input of amplifier Channel 1. Input bias current 1 pA typical; input voltage range VDD- to VDD+ - 1.5 V.
3	1IN+	input	Non-inverting input of amplifier Channel 1. Common-mode input voltage range includes the negative rail (VDD-) up to VDD+ - 1.5 V.
4	VDD-/GND	power_in	Negative (lowest) supply. In split-supply operation VDD- can be down to -8 V; in single-supply operation this pin is GND. Total current out of VDD- rated ±50 mA max.
5	2IN+	input	Non-inverting input of amplifier Channel 2. Common-mode input voltage range includes the negative rail (VDD-) up to VDD+ - 1.5 V.
6	2IN-	input	Inverting input of amplifier Channel 2. Input bias current 1 pA typical; input voltage range VDD- to VDD+ - 1.5 V.
7	2OUT	output	Output of amplifier Channel 2. Rail-to-rail output stage capable of ±50 mA output current.
8	VDD+	power_in	Positive (highest) supply. Rated up to 8 V (16 V total supply span). Total current into VDD+ rated ±50 mA max.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2272idr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlc2272idr-etched.step`	1.8 MB	You want the part with `TLC2272IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 465 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.
