LT1801CS8#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, swinging within 20mV of either supply rail (rail-to-rail output).
2	-IN A	input	Inverting input of amplifier A; input range includes both supply rails.
3	+IN A	input	Non-inverting input of amplifier A; input range includes both supply rails.
4	V-	power_in	Negative supply (or ground in single-supply operation); total supply V+ to V- is 2.3V to 12.6V max.
5	+IN B	input	Non-inverting input of amplifier B; input range includes both supply rails.
6	-IN B	input	Inverting input of amplifier B; input range includes both supply rails.
7	OUT B	output	Output of amplifier B, swinging within 20mV of either supply rail (rail-to-rail output).
8	V+	power_in	Positive supply; total supply voltage V+ to V- is 2.3V minimum operating and 12.6V absolute maximum.
