ADA4522-1ARZ-R7

Analog Devices · Precision Op Amps · SOIC-8

ADA4522-1ARZ-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 NIC unconnected Not internally connected, per the datasheet's NIC definition.
2 -IN input Inverting input; input pins are rated for (V−) − 300 mV to (V+) + 300 mV, and input current must be limited to ±10 mA when the input exceeds the supply rail by 300 mV.
3 +IN input Noninverting input with the same absolute maximum input range of (V−) − 300 mV to (V+) + 300 mV.
4 V- power_in Negative supply voltage; supports single-supply operation from 4.5 V to 55 V or dual supplies of ±2.25 V to ±27.5 V, with a 60 V absolute maximum supply rating.
5 NIC unconnected Not internally connected, per the datasheet's NIC definition.
6 OUT output Output that swings rail-to-rail and tolerates indefinite short-circuit to ground.
7 V+ power_in Positive supply voltage; same supply range as V−, with a 60 V absolute maximum supply rating.
8 NIC unconnected Not internally connected, per the datasheet's NIC definition.
