TLV2313QDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUT A	output	Channel A amplifier output; the datasheet states it swings to within about 5 mV of the supply rails with a 100 kΩ load.
2	-IN A	input	Channel A inverting input; the common-mode voltage range extends 0.2 V beyond each supply rail, (V-) - 0.2 V to (V+) + 0.2 V.
3	+IN A	input	Channel A noninverting input; the common-mode voltage range is (V-) - 0.2 V to (V+) + 0.2 V and typical input bias current is ±1 pA.
4	V-	power_in	Negative (lowest) power supply; the rated total supply (V+) - (V-) is 1.8 V to 5.5 V.
5	+IN B	input	Channel B noninverting input; the common-mode voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
6	-IN B	input	Channel B inverting input; the common-mode voltage range is (V-) - 0.2 V to (V+) + 0.2 V.
7	OUT B	output	Channel B amplifier output; the datasheet states it swings to within about 5 mV of the supply rails with a 100 kΩ load.
8	V+	power_in	Positive (highest) power supply; the rated total supply (V+) - (V-) is 1.8 V to 5.5 V and absolute maximum is 7 V.
