TLC2272AIDR 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; ±50 mA max output current, short-circuit protected to either supply.
2	1IN-	input	Inverting input of amplifier channel 1. High-impedance CMOS input; input current typ 1 pA. Must stay within VDD- to VDD+.
3	1IN+	input	Non-inverting input of amplifier channel 1. Common-mode input range includes the negative supply rail; high-impedance CMOS input, typ 1 pA bias current.
4	VDD-/GND	power_in	Negative (lowest) supply pin. Ties to GND in single-supply operation or to the negative rail in split-supply operation. Recommended operating supply
5	2IN+	input	Non-inverting input of amplifier channel 2. Common-mode input range includes the negative rail; high-impedance CMOS input.
6	2IN-	input	Inverting input of amplifier channel 2. High-impedance CMOS input; typ 1 pA input bias current.
7	2OUT	output	Output of amplifier channel 2. Rail-to-rail output stage; ±50 mA max output current, short-circuit protected.
8	VDD+	power_in	Positive (highest) supply pin. Recommended supply voltage 2.2 V to 8 V (or up to ±8 V split). Absolute maximum 8 V with respect to VDD-.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2272aidr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlc2272aidr-etched.step`	1.9 MB	You want the part with `TLC2272AIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 491 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.
