AD8418AWHRMZ 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	−IN	input	Negative input of the shunt amplifier; common-mode range −2 V to +70 V continuous, −3 V to +80 V survival.
2	GND	power_in	Ground.
3	VREF2	input	Reference input 2, tied through an internal 100 kΩ resistor to the offset node; operating range is GND to VS and it is functionally identical to VREF1.
4	NC	unconnected	No connect; do not connect to this pin.
5	OUT	output	Buffered output with fixed gain of 20 V/V, output range 0.032 V to VS − 0.032 V at RL = 25 kΩ, up to 500 pF capacitive load.
6	VS	power_in	Supply voltage, 2.7 V to 5.5 V operating range (6 V absolute maximum).
7	VREF1	input	Reference input 1, tied through an internal 100 kΩ resistor to the offset node; operating range is GND to VS and it is functionally identical to VREF2.
8	+IN	input	Positive input of the shunt amplifier; common-mode range −2 V to +70 V continuous, −3 V to +80 V survival.
