TSV634IPT 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	Out1	output	Output of amplifier channel 1. Rail-to-rail CMOS output stage, capable of sinking/sourcing ~6 mA (typ) into a load referenced to VCC/2; drives loads down to R_L = 2 kΩ with C_L up to 100 pF while remaining unity-gain stable.
2	In1-	input	Inverting input of amplifier channel 1. High-impedance CMOS input, input bias current 1 pA typ (100 pA max over temp); common-mode range extends from (VCC-)-0.1 V to (VCC+)+0.1 V.
3	In1+	input	Non-inverting input of amplifier channel 1. High-impedance CMOS input; must remain within (VCC-)-0.2 V to (VCC+)+0.2 V absolute-max and (VCC-)-0.1 V to (VCC+)+0.1 V operating common-mode range.
4	VCC+	power_in	Positive supply rail, shared by all four amplifier channels. Operating range 1.5 V to 5.5 V; absolute maximum 6 V. Decouple locally with a small ceramic capacitor to VCC-.
5	In2+	input	Non-inverting input of amplifier channel 2. Rail-to-rail CMOS input with 1 pA typical bias current.
6	In2-	input	Inverting input of amplifier channel 2. Rail-to-rail CMOS input; keep within (VCC-)-0.2 V to (VCC+)+0.2 V absolute-max.
7	Out2	output	Output of amplifier channel 2. Rail-to-rail push-pull output, ~6 mA source/sink drive (typ 10-12 mA); slew rate 0.27 V/µs typ at R_L=2 kΩ / C_L=100 pF.
8	Out3	output	Output of amplifier channel 3. Rail-to-rail push-pull output with same drive characteristics as the other channels.
9	In3-	input	Inverting input of amplifier channel 3. High-impedance CMOS input, 1 pA typ bias current.
10	In3+	input	Non-inverting input of amplifier channel 3. Rail-to-rail CMOS input.
11	VCC-	power_in	Negative supply / ground rail, shared by all four channels. For single-supply operation tie to system ground; for dual-supply, this is the negative rail. All input/output voltages are referenced to this node.
12	In4+	input	Non-inverting input of amplifier channel 4. Rail-to-rail CMOS input, 1 pA typ bias current.
13	In4-	input	Inverting input of amplifier channel 4. High-impedance CMOS input.
14	Out4	output	Output of amplifier channel 4. Rail-to-rail push-pull output; unity-gain stable with 100 pF capacitive load.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tsv634ipt.step`	194 KB	You want the bare part, or you mark your own boards.
`tsv634ipt-etched.step`	2.1 MB	You want the part with `TSV634IPT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 533 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.
