TLV2170IDR 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	OUT A	output	Output of amplifier channel A. Rail-to-rail output stage capable of driving a 200-pF capacitive load while remaining unity-gain stable.
2	-IN A	input	Inverting (negative) input of amplifier channel A. High-impedance input with RFI-filtered EMI-hardened front end; typical input bias current 10 pA.
3	+IN A	input	Noninverting (positive) input of amplifier channel A. Input common-mode range extends 100 mV below the negative supply rail and to within 2 V of the positive rail for normal operation.
4	V-	power_in	Negative (lowest) power supply. Connect to GND for single-supply operation or to the negative rail for split-supply operation. Total supply range 2.7 V to 36 V (±1.35 V to ±18 V).
5	+IN B	input	Noninverting (positive) input of amplifier channel B. Same common-mode range and low-bias EMI-hardened behavior as channel A inputs.
6	-IN B	input	Inverting (negative) input of amplifier channel B. High-impedance input with RFI-filtered EMI-hardened front end.
7	OUT B	output	Output of amplifier channel B. Rail-to-rail output stage capable of driving a 200-pF capacitive load while remaining unity-gain stable.
8	V+	power_in	Positive (highest) power supply. Supports 2.7 V to 36 V single-supply or up to ±18 V split-supply operation. Bypass to V- with a 0.1 µF ceramic capacitor placed close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv2170idr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlv2170idr-etched.step`	1.6 MB	You want the part with `TLV2170IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 433 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.
