LT1490ACMS8#PBF from Analog Devices, in a MSOP-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 to within 10mV max of V- and can source or sink heavy loads at up to 20mA.
2	-IN A	input	Inverting input of amplifier A, whose input range includes both supplies and which is protected by an internal 1kΩ series resistor for faults up to 15V below V-.
3	+IN A	input	Non-inverting input of amplifier A, which operates with its common-mode range extending 44V above V- independent of V+ and is protected for faults up to 15V below V-.
4	V-	power_in	Negative supply pin; the part operates on single or split supplies with a total supply voltage of 2V to 44V, and should be bypassed close to the pin.
5	+IN B	input	Non-inverting input of amplifier B, which operates with its common-mode range extending 44V above V- independent of V+ and is protected for faults up to 15V below V-.
6	-IN B	input	Inverting input of amplifier B, whose input range includes both supplies and which is protected by an internal 1kΩ series resistor for faults up to 15V below V-.
7	OUT B	output	Output of amplifier B, which swings to within 10mV max of V- and can source or sink heavy loads at up to 20mA.
8	V+	power_in	Positive supply pin; total supply (V+ to V-) is limited to 44V absolute maximum and the part is reverse-battery protected up to 18V.
