ADR440ARMZ from Analog Devices, in a MSOP-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 | DNC | unconnected | Do Not Connect; the datasheet says nothing should be connected to this pin. |
| 2 | VIN | power_in | Input voltage connection, with a supply operating range of 3 V to 18 V for the ADR440 and a required headroom of 500 mV above VOUT. |
| 3 | NIC | unconnected | Not internally connected; the pin is not connected inside the device. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM | passive | Output voltage trim; a potentiometer from VOUT to GND with its wiper on TRIM adjusts the output over a ±0.5% range without compromising performance. |
| 6 | VOUT | power_out | Output voltage that can source up to 10 mA and sink up to −5 mA, with 0.1 µF capacitors on input and output required for stability. |
| 7 | NIC | unconnected | Not internally connected; the pin is not connected inside the device. |
| 8 | DNC | unconnected | Do Not Connect; the datasheet says nothing should be connected to this pin. |
