TLV2634IPWR from UMW, in a TSSOP-14. 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	Op-amp channel 1 output. Rail-to-rail; sources ~14 mA @ VDD=2.7 V, ~28 mA @ VDD=5 V; short-circuit current ~50-95 mA.
2	1IN-	input	Op-amp channel 1 inverting input. Input range GND to VDD-1 V; input bias current ~1 pA typ.
3	1IN+	input	Op-amp channel 1 non-inverting input. Input range GND to VDD-1 V.
4	VDD	power_in	Positive supply voltage. Single-supply 2.7 V to 5.5 V (absolute max 6 V); split-supply ±1.35 V to ±2.75 V. Supply current ~730 μA/channel active, ~4 μA/channel in shutdown.
5	2IN+	input	Op-amp channel 2 non-inverting input. Input range GND to VDD-1 V.
6	2IN-	input	Op-amp channel 2 inverting input. Input range GND to VDD-1 V.
7	2OUT	output	Op-amp channel 2 output. Rail-to-rail; short-circuit current up to ~95 mA @ VDD=5 V.
8	3OUT	output	Op-amp channel 3 output. Rail-to-rail.
9	3IN-	input	Op-amp channel 3 inverting input. Input range GND to VDD-1 V.
10	3IN+	input	Op-amp channel 3 non-inverting input. Input range GND to VDD-1 V.
11	GND	power_in	Ground / negative supply reference. Tied to 0 V in single-supply operation or to the negative rail in split-supply operation.
12	4IN+	input	Op-amp channel 4 non-inverting input. Input range GND to VDD-1 V.
13	4IN-	input	Op-amp channel 4 inverting input. Input range GND to VDD-1 V.
14	4OUT	output	Op-amp channel 4 output. Rail-to-rail.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv2634ipwr.step`	194 KB	You want the bare part, or you mark your own boards.
`tlv2634ipwr-etched.step`	2.3 MB	You want the part with `TLV2634IPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 594 faces against 237 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.
