LT6221IS8#PBF 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 per the datasheet features.
2	-IN A	input	Inverting input of amplifier A; input current is limited to ±10mA absolute maximum and input voltage to ±VS.
3	+IN A	input	Non-inverting input of amplifier A; input common mode range includes both supply rails and inputs can be driven beyond the supplies without damage or phase reversal.
4	VS-	power_in	Negative supply rail; total supply voltage (VS- to VS+) is specified from 2.2V to 12.6V, with 12.6V as the absolute maximum.
5	+IN B	input	Non-inverting input of amplifier B; input common mode range includes both supply rails and inputs can be driven beyond the supplies without damage or phase reversal.
6	-IN B	input	Inverting input of amplifier B; input current is limited to ±10mA absolute maximum and input voltage to ±VS.
7	OUT B	output	Output of amplifier B, which swings within 10mV of either supply rail per the datasheet features.
8	VS+	power_in	Positive supply rail; total supply voltage (VS- to VS+) is specified from 2.2V to 12.6V, with 12.6V as the absolute maximum.
