AD8227ARMZ

Analog Devices · Instrumentation OpAmps · MSOP-8

AD8227ARMZ 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 instrumentation amplifier; the input range can go below ground and the inputs are protected beyond the supplies, with input voltages up to 40 V from the opposite supply rail.
2 RG passive Gain-setting pin; place the gain resistor between pins 2 and 3, with G = 5 + 80 kΩ/RG and the gain defaulting to 5 when no resistor is used.
3 RG passive Gain-setting pin; place the gain resistor between pins 2 and 3, with G = 5 + 80 kΩ/RG and the gain defaulting to 5 when no resistor is used.
4 +IN input Positive input of the instrumentation amplifier; the input range can go below ground and the inputs are protected beyond the supplies, with input voltages up to 40 V from the opposite supply rail.
5 -VS power_in Negative supply; the part operates from ±1.5 V to ±18 V dual supply or 2.2 V to 36 V single supply.
6 REF input Reference pin that must be driven by low impedance (below 2 Ω for best performance) and should not exceed either supply by more than 0.3 V.
7 VOUT output Output with rail-to-rail swing, developed with respect to the REF pin potential; output short-circuit current is indefinite.
8 +VS power_in Positive supply; the part operates from ±1.5 V to ±18 V dual supply or 2.2 V to 36 V single supply.
