AD8227ARZ-R7

Analog Devices · Instrumentation OpAmps · SOIC-8

AD8227ARZ-R7 from Analog Devices, 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 -IN input Negative input; input voltages can be up to 40 V from the opposite supply rail, and the absolute maximum voltage at -IN is -VS + 40 V.
2 RG passive Gain-setting pin; place the gain resistor between pins 2 and 3 (G = 5 with no resistor, G = 5 + 80 kΩ/RG).
3 RG passive Gain-setting pin; place the gain resistor between pins 2 and 3 (G = 5 with no resistor, G = 5 + 80 kΩ/RG).
4 +IN input Positive input; input voltages can be up to 40 V from the opposite supply rail, and the minimum voltage at +IN is +VS - 40 V.
5 -VS power_in Negative supply; the part operates from ±1.5 V to ±18 V dual supplies or 2.2 V to 36 V single supply, with supply voltage rated at ±18 V.
6 REF input Reference; must be driven by a low impedance (source impedance below 2 Ω is recommended) and should not exceed either +VS or -VS by more than 0.3 V.
7 VOUT output Output; rail-to-rail output, and the output short-circuit current is indefinite.
8 +VS power_in Positive supply; the part operates from ±1.5 V to ±18 V dual supplies or 2.2 V to 36 V single supply, with supply voltage rated at ±18 V.
