ADA4522-2ARZ

Analog Devices · Operational Amplifier · SOIC-8

ADA4522-2ARZ 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	OUT A	output	Output of channel A; the datasheet gives no electrical limits for this pin beyond the absolute maximum ratings, including indefinite output short-circuit duration to ground.
2	-IN A	input	Inverting input of channel A; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current must be limited to ±10 mA whenever the input exceeds the supply rail by 300 mV.
3	+IN A	input	Noninverting input of channel A; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current must be limited to ±10 mA whenever the input exceeds the supply rail by 300 mV.
4	V-	power_in	Negative supply voltage; the op amp supplies should be applied simultaneously, or the positive supply first if that is not possible.
5	+IN B	input	Noninverting input of channel B; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current must be limited to ±10 mA whenever the input exceeds the supply rail by 300 mV.
6	-IN B	input	Inverting input of channel B; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current must be limited to ±10 mA whenever the input exceeds the supply rail by 300 mV.
7	OUT B	output	Output of channel B; the datasheet gives no electrical limits for this pin beyond the absolute maximum ratings, including indefinite output short-circuit duration to ground.
8	V+	power_in	Positive supply voltage; the absolute maximum supply voltage is 60 V, and the device operates from 4.5 V to 55 V.
