ADA4530-1ARZ

Analog Devices · Operational Amplifier · SOIC-8

ADA4530-1ARZ 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 +IN input Non-inverting input, which also feeds the guard-ring buffer; the input common-mode range is V− to V+ − 1.5 V, and operation outside that range is not recommended.
2 GRD output Guard-ring buffer output that drives the guard around the high-impedance input; it has about 1 kΩ output resistance, and the datasheet advises against loading it except for insulation-resistance guarding, since each 1 nA of load adds 1 µV of guard error per kΩ.
3 IC passive Internal connection that must be tied to V− or left unconnected.
4 V− power_in Negative supply voltage; the part operates from 4.5 V to 16 V total (±2.25 V to ±8 V dual supply).
5 V+ power_in Positive supply voltage; the part operates from 4.5 V to 16 V total (±2.25 V to ±8 V dual supply), with an absolute maximum supply of 17 V.
6 OUT output Rail-to-rail output that typically swings to within 30 mV of the supply rails with a 10 kΩ load.
7 GRD output Guard-ring buffer output, the second guard pin, which can be connected to the guard ring; the datasheet advises against driving any load other than insulation-resistance guarding through the buffer.
8 −IN input Inverting input; the input current must be limited to 10 mA and the differential input voltage is rated to ±0.7 V.
