LT1494IMS8#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	NC	unconnected	No connect pin with no internal function stated in the datasheet.
2	-IN	input	Inverting input with a single-supply input range of 0V to 36V (over-the-top, operates above V+), differential input voltage limited to 36V and input current to ±10mA.
3	+IN	input	Non-inverting input with a single-supply input range of 0V to 36V (over-the-top, operates above V+), differential input voltage limited to 36V and input current to ±10mA.
4	V-	power_in	Negative supply (ground in single-supply use); total supply V+ to V- is 2.2V to 36V and reverse battery protected to 18V.
5	NC	unconnected	No connect pin with no internal function stated in the datasheet.
6	OUT	output	Rail-to-rail output that sources and sinks 500µA load current, with continuous short-circuit duration (ISC 0.7mA min, 1.3mA max at 25°C, 5V).
7	V+	power_in	Positive supply, 2.2V to 36V total supply, with 1.5µA maximum supply current per amplifier at 25°C and 5V.
8	NC	unconnected	No connect pin with no internal function stated in the datasheet.
