ADA4522-1ARZ

Analog Devices · Precision Op Amps · SOIC-8

ADA4522-1ARZ 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 NIC unconnected Not internally connected; the datasheet specifies no function for this pin.
2 -IN input Inverting input; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current should be limited to ±10 mA when the input exceeds the supply rail by 300 mV.
3 +IN input Noninverting input; input voltage must stay between (V-) - 300 mV and (V+) + 300 mV, and input current should be limited to ±10 mA when the input exceeds the supply rail by 300 mV.
4 V- power_in Negative supply voltage; operating supply range is 4.5 V to 55 V single-supply or ±2.25 V to ±27.5 V dual-supply, with an absolute maximum supply voltage of 60 V.
5 NIC unconnected Not internally connected; the datasheet specifies no function for this pin.
6 OUT output Amplifier output, a rail-to-rail output stage; the output is short-circuit protected to ground for an indefinite duration.
7 V+ power_in Positive supply voltage; operating supply range is 4.5 V to 55 V single-supply or ±2.25 V to ±27.5 V dual-supply, with an absolute maximum supply voltage of 60 V.
8 NIC unconnected Not internally connected; the datasheet specifies no function for this pin.
