ADR441ARMZ-REEL7 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 states not to connect anything to this pin. |
| 2 | VIN | power_in | Input voltage connection; the ADR441 operates from 3 V to 18 V and needs at least 500 mV of headroom above VOUT. |
| 3 | NIC | unconnected | Not internally connected; the pin has no internal connection. |
| 4 | GND | power_in | Ground reference pin for the reference. |
| 5 | TRIM | passive | Output voltage trim; a potentiometer between VOUT and GND with its wiper on this pin adjusts the output over a ±0.5% range. |
| 6 | VOUT | power_out | Reference output (2.500 V for the ADR441); the device sources up to 10 mA and sinks up to −5 mA. |
| 7 | NIC | unconnected | Not internally connected; the pin has no internal connection. |
| 8 | DNC | unconnected | Do not connect; the datasheet states not to connect anything to this pin. |
