TLV27L2IDR 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 A output. Rail-to-rail CMOS output stage; typical swing from rail 50-420 mV depending on load and supply. Max output current 100 mA (absolute max).
2	1IN-	input	Amplifier A inverting input. BiMOS high-impedance input (~1000 GΩ differential, ~8 pF common-mode capacitance); input bias current ~1 pA typical.
3	1IN+	input	Amplifier A non-inverting input. Input common-mode voltage range −0.2 V to (VS − 1.2 V); high impedance BiMOS input.
4	GND	power_in	Negative supply / ground pin (V−). In single-supply operation tie to GND; in dual-supply operation connect to the negative rail (down to −8 V). Referenced by all absolute-maximum voltages (Note 1).
5	2IN+	input	Amplifier B non-inverting input. Input common-mode voltage range −0.2 V to (VS − 1.2 V); high-impedance BiMOS input.
6	2IN-	input	Amplifier B inverting input. High-impedance BiMOS input; input bias current ~1 pA typical.
7	2OUT	output	Amplifier B output. Rail-to-rail CMOS output stage; drives up to 100 mA (absolute max), typical output current 400 µA at 0.5 V from rail with VS = 2.7 V.
8	VDD	power_in	Positive supply pin (V+). Operating range 2.7 V to 16 V single-supply (±1.35 V to ±8 V dual). Absolute max 16.5 V. Recommend a 0.1 µF ceramic in parallel with a 6.8 µF tantalum placed within 0.1 in of the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv27l2idr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlv27l2idr-etched.step`	1.6 MB	You want the part with `TLV27L2IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 413 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.
