LT6221CS8#TRPBF from Analog Devices, in a SO-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	Output of amplifier A, which swings within 10mV of either supply rail.
2	-IN A	input	Inverting input of amplifier A; the inputs can be driven beyond the supplies without damage or phase reversal of the output.
3	+IN A	input	Non-inverting input of amplifier A; the input range includes both supply rails.
4	VS-	power_in	Negative supply rail; supplies from 2.2V to 12.6V are supported.
5	+IN B	input	Non-inverting input of amplifier B; the input range includes both supply rails.
6	-IN B	input	Inverting input of amplifier B; the inputs can be driven beyond the supplies without damage or phase reversal of the output.
7	OUT B	output	Output of amplifier B, which swings within 10mV of either supply rail.
8	VS+	power_in	Positive supply rail; supplies from 2.2V to 12.6V are supported.
