LT1678CS8#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; the output swings to within about 170mV of either rail at 3V and 5V supplies, and shorts to ground are indefinite-duration per the Absolute Maximum Ratings.
2	-IN A	input	Inverting input of amplifier A; the inputs are protected by back-to-back diodes and may be driven 0.3V beyond either rail, with differential input current limited to ±25mA.
3	+IN A	input	Non-inverting input of amplifier A; the common-mode input range extends from 0.1V below V- to 0.1V above the supply at 25°C, with no phase inversion.
4	V-	power_in	Negative supply rail; the part operates single-supply from 2.7V to 36V (with V- at GND) or split supplies of ±1.7V to ±18V, with ±18V as the absolute maximum supply voltage.
5	+IN B	input	Non-inverting input of amplifier B; the inputs are protected by back-to-back diodes and may be driven 0.3V beyond either rail.
6	-IN B	input	Inverting input of amplifier B; the inputs are protected by back-to-back diodes and may be driven 0.3V beyond either rail, with differential input current limited to ±25mA.
7	OUT B	output	Output of amplifier B; the output swings to within about 170mV of either rail and the short-circuit duration is indefinite per the Absolute Maximum Ratings.
8	V+	power_in	Positive supply rail; the part operates from 2.7V to 36V single supply, with a ±18V absolute maximum supply voltage.
