GS6004-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	Output of amplifier A. Rail-to-rail output; swings within ~10mV of the supply rails under light loads (>100kΩ) and within ~60mV under 10kΩ loads. Source/sink capability ~84/75mA typ into VS/2.
2	INA-	input	Inverting input of amplifier A. Rail-to-rail input; common-mode range extends 100mV beyond supply rails (VSS-0.1V to VDD+0.1V). Input bias current 1pA typ.
3	INA+	input	Non-inverting input of amplifier A. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
4	VDD	power_in	Positive supply rail. Single-supply operating range +1.8V to +6V (absolute max +7.5V referenced to VSS). Bypass with 0.1µF ceramic capacitor close to the pin.
5	INB+	input	Non-inverting input of amplifier B. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
6	INB-	input	Inverting input of amplifier B. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
7	OUTB	output	Output of amplifier B. Rail-to-rail output; swings within ~10mV of supply rails under light loads.
8	OUTC	output	Output of amplifier C. Rail-to-rail output; swings within ~10mV of supply rails under light loads.
9	INC-	input	Inverting input of amplifier C. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
10	INC+	input	Non-inverting input of amplifier C. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
11	VSS	power_in	Negative supply / ground return. Tie to ground in single-supply operation, or to negative rail in dual-supply operation (up to ±3V). Bypass with 0.1µF ceramic in dual-supply use.
12	IND+	input	Non-inverting input of amplifier D. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
13	IND-	input	Inverting input of amplifier D. Rail-to-rail input; common-mode range VSS-0.1V to VDD+0.1V. Input bias current 1pA typ.
14	OUTD	output	Output of amplifier D. Rail-to-rail output; swings within ~10mV of supply rails under light loads.
