TLV2313IDR from UMW, in a SOP-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 capable, short-circuit protected to ground.
2	-IN_A	input	Inverting input of amplifier channel A. Rail-to-rail input; input voltage range (V-)-0.2 V to (V+)+0.2 V. Diode-clamped to supply rails; limit input current to <=10 mA if driven beyond rails.
3	+IN_A	input	Noninverting input of amplifier channel A. Rail-to-rail input; input voltage range (V-)-0.2 V to (V+)+0.2 V. Diode-clamped to supply rails.
4	V-	power_in	Negative (lowest) power-supply pin. Connect to ground for single-supply operation or to the negative rail for dual-supply. Total supply (V+ minus V-) is 1.8 V to 5.5 V (7 V absolute max).
5	+IN_B	input	Noninverting input of amplifier channel B. Rail-to-rail input; input voltage range (V-)-0.2 V to (V+)+0.2 V. Diode-clamped to supply rails.
6	-IN_B	input	Inverting input of amplifier channel B. Rail-to-rail input; input voltage range (V-)-0.2 V to (V+)+0.2 V. Diode-clamped to supply rails.
7	OUT_B	output	Output of amplifier channel B. Rail-to-rail output capable, short-circuit protected to ground.
8	V+	power_in	Positive (highest) power-supply pin. Operating range 1.8 V to 5.5 V referenced to V-; absolute maximum supply 7 V. Bypass locally with a 0.1 µF ceramic capacitor to V-.

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

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv2313idr.step`	122 KB	You want the bare part, or you mark your own boards.
`tlv2313idr-etched.step`	1.9 MB	You want the part with `TLV2313IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 483 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.
