TLC2272CDR 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 1. Rail-to-rail output stage, capable of swinging within millivolts of VDD+ and VDD-/GND. Output current limited to +/-50 mA absolute maximum.
2	1IN-	input	Inverting input of amplifier 1. High-impedance CMOS input with 1 pA typical bias current. Input voltage range includes the negative rail (VDD-/GND) up to VDD+ - 1.5 V.
3	1IN+	input	Non-inverting input of amplifier 1. High-impedance CMOS input with 1 pA typical bias current. Common-mode range includes the negative rail.
4	VDD-/GND	power_in	Negative supply rail (split supply) or ground (single supply). For split-supply operation accepts -2.2 V to -8 V. For single-supply operation tie to GND; total supply must not exceed 16 V.
5	2IN+	input	Non-inverting input of amplifier 2. High-impedance CMOS input with 1 pA typical bias current. Common-mode range includes the negative rail.
6	2IN-	input	Inverting input of amplifier 2. High-impedance CMOS input with 1 pA typical bias current.
7	2OUT	output	Output of amplifier 2. Rail-to-rail output stage. Output current limited to +/-50 mA absolute maximum.
8	VDD+	power_in	Positive supply rail. Recommended range +2.2 V to +8 V (split supply) or 4.4 V to 16 V total between VDD+ and VDD-. Absolute maximum 8 V (split) with total current into VDD+ limited to +/-50 mA.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2272cdr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlc2272cdr-etched.step`	1.9 MB	You want the part with `TLC2272CDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 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.
