TLC2252AIDR 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	Amplifier 1 output. Rail-to-rail output stage; short-circuit current limited (output current ±50 mA absolute max).
2	1IN-	input	Amplifier 1 inverting input. High impedance CMOS input, ~1 pA typical input bias current. Common-mode range includes the negative rail (VDD- to VDD+ − 1.5 V).
3	1IN+	input	Amplifier 1 non-inverting input. High impedance CMOS input, ~1 pA typical input bias current. Common-mode range includes the negative rail (VDD- to VDD+ − 1.5 V).
4	VDD-/GND	power_in	Negative supply rail (or ground for single-supply operation). Fully specified for single-supply and split-supply operation; supply range ±2.2 V to ±8 V (split) or 4.4 V to 16 V (single).
5	2IN+	input	Amplifier 2 non-inverting input. High impedance CMOS input, ~1 pA typical input bias current. Common-mode range includes the negative rail (VDD- to VDD+ − 1.5 V).
6	2IN-	input	Amplifier 2 inverting input. High impedance CMOS input, ~1 pA typical input bias current. Common-mode range includes the negative rail (VDD- to VDD+ − 1.5 V).
7	2OUT	output	Amplifier 2 output. Rail-to-rail output stage; short-circuit current limited (output current ±50 mA absolute max).
8	VDD+	power_in	Positive supply rail. Absolute max 8 V (split) or 16 V (single). Recommended operating supply ±2.2 V to ±8 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlc2252aidr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlc2252aidr-etched.step`	2.1 MB	You want the part with `TLC2252AIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 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.
