GS8044-TR from Gainsil, 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	OUTA	output	Amplifier A output. Rail-to-rail output swing, typically within ~50 mV of the supply rails driving light loads (>50 kΩ); source/sink up to ~20 mA.
2	INA-	input	Amplifier A inverting input. Rail-to-rail input; common-mode range VSS-0.1 V to VDD+0.1 V. Input bias current 1 pA typ.
3	INA+	input	Amplifier A non-inverting input. Rail-to-rail input; common-mode range VSS-0.1 V to VDD+0.1 V.
4	VDD	power_in	Positive supply voltage, +1.4 V to +5.5 V (single-supply), or +0.7 V to +2.75 V (dual). Bypass with 0.1 μF ceramic close to the pin. Absolute maximum VDD-to-VSS is +7.5 V.
5	INB+	input	Amplifier B non-inverting input. Rail-to-rail input; common-mode range VSS-0.1 V to VDD+0.1 V.
6	INB-	input	Amplifier B inverting input. Rail-to-rail input; input bias current 1 pA typ.
7	OUTB	output	Amplifier B output. Rail-to-rail; source/sink up to ~20 mA into 10 Ω to VS/2.
8	OUTC	output	Amplifier C output. Rail-to-rail output swing.
9	INC-	input	Amplifier C inverting input. Rail-to-rail input; input bias current 1 pA typ.
10	INC+	input	Amplifier C non-inverting input. Rail-to-rail input.
11	VSS	power_in	Negative supply / ground reference. Tie to 0 V in single-supply operation; bypass with 0.1 μF in dual-supply operation.
12	IND+	input	Amplifier D non-inverting input. Rail-to-rail input; common-mode range VSS-0.1 V to VDD+0.1 V.
13	IND-	input	Amplifier D inverting input. Rail-to-rail input; input bias current 1 pA typ.
14	OUTD	output	Amplifier D output. Rail-to-rail output swing.

CAD (KiCad official)

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gs8044-tr.step`	194 KB	You want the bare part, or you mark your own boards.
`gs8044-tr-etched.step`	2.3 MB	You want the part with `GS8044-TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 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.
