ADR4525ARZ 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 | Internally not connected; this pin has no internal connection and is not part of the signal path. |
| 2 | VIN | power_in | Input voltage connection; the datasheet specifies VIN = 3 V to 15 V for the ADR4525 and an absolute maximum supply voltage of 16 V. |
| 3 | NIC | unconnected | Internally not connected; this pin has no internal connection and is not part of the signal path. |
| 4 | GND | power_in | Ground reference for the reference circuit. |
| 5 | NIC | unconnected | Internally not connected; this pin has no internal connection and is not part of the signal path. |
| 6 | VOUT | power_out | Reference output voltage (2.500 V nominal for ADR4525); rated for +10 mA source and −10 mA sink, and the datasheet recommends connecting VOUT directly to the load for highest output accuracy. |
| 7 | NIC | unconnected | Internally not connected; this pin has no internal connection and is not part of the signal path. |
| 8 | DNC | unconnected | Do not connect; this pin must be left unconnected and not wired externally. |
