AD8226ARMZ 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 differential input; the input stage is PNP so input bias current flows out of this pin and needs a DC return path to ground, and the input tolerates voltages up to 40 V beyond the supply rails.
2 RG passive Gain-setting pin; a single external resistor RG connected between pins 2 and 3 sets the gain as G = 1 + (49.4 kΩ/RG), and no resistor gives G = 1.
3 RG passive Gain-setting pin; a single external resistor RG connected between pins 2 and 3 sets the gain as G = 1 + (49.4 kΩ/RG), and no resistor gives G = 1.
4 +IN input Positive differential input; the input operating voltage range is −VS − 0.1 V to +VS − 0.8 V at 25 °C (typical, ±15 V supplies), so signals near the rails must be kept within this range.
5 -VS power_in Negative supply; use ±1.35 V to ±18 V for dual supply, or connect to 0 V for single-supply operation from 2.2 V to 36 V.
6 REF input Reference input that sets the output level relative to this pin; it must be driven from a low impedance (source impedance below 2 Ω recommended) and must not exceed ±VS by more than 0.3 V.
7 VOUT output Output referenced to the voltage on REF; the short-circuit current is 13 mA as stated in the specification table.
8 +VS power_in Positive supply; operating range is 2.2 V to 36 V single-supply or ±1.35 V to ±18 V dual-supply.
