TP2314-SR from 3PEAK, in a SOP-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 stage capable of ~70 mA drive (1 V drop), short-circuit current typ 130 mA.
2	-INA	input	Amplifier A inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V; typ input bias current 0.3 pA at 27 °C.
3	+INA	input	Amplifier A non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V.
4	+Vs	power_in	Positive supply rail. Single-supply 2.2 V to 5.5 V (or ±1.1 V to ±2.75 V split). Bypass locally with 100 nF ceramic. Absolute max V+−V− = 7 V.
5	+INB	input	Amplifier B non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V.
6	-INB	input	Amplifier B inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C.
7	OUTB	output	Amplifier B output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop).
8	OUTC	output	Amplifier C output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop).
9	-INC	input	Amplifier C inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C.
10	+INC	input	Amplifier C non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V.
11	-Vs	power_in	Negative supply rail / ground for single-supply operation. Tie to GND for single-supply use, or to the negative rail for split supplies. Absolute max V+−V− = 7 V.
12	+IND	input	Amplifier D non-inverting input. Rail-to-rail input; common-mode range V−−0.1 V to V+−0.1 V.
13	-IND	input	Amplifier D inverting input. Rail-to-rail input; typ input bias current 0.3 pA at 27 °C.
14	OUTD	output	Amplifier D output. Rail-to-rail output stage capable of ~70 mA drive (1 V drop).
