MAX4200ESA+ from Maxim Integrated, in a SOIC-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	N.C.	unconnected	No Connection; pin is not internally connected.
2	N.C.	unconnected	No Connection; pin is not internally connected.
3	IN	input	Buffer input; the input looks like a 500kΩ resistor in parallel with 2pF, and the input impedance decreases as the output load decreases.
4	VEE	power_in	Negative power supply; operates from ±4V to ±5.5V dual supplies and should be bypassed to the ground plane with a 0.1µF capacitor placed as close to the pin as possible.
5	N.C.	unconnected	No Connection; pin is not internally connected.
6	OUT	output	Buffer output; the output resistance of the MAX4200 is 8Ω (DC) and output current is ±90mA with RL = 30Ω.
7	VCC	power_in	Positive power supply; operates from ±4V to ±5.5V dual supplies and should be bypassed to the ground plane with a 0.1µF capacitor placed as close to the pin as possible.
8	N.C.	unconnected	No Connection; pin is not internally connected.
