ADR444ARMZ-REEL7
Analog Devices · Voltage References · MSOP-8
ADR444ARMZ-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 says do not connect to this pin. |
| 2 | VIN | power_in | Input voltage connection; for the ADR444 the supply range is 4.6 V to 18 V, with input at least (VOUT + 500 mV), and a 0.1 µF input capacitor is required. |
| 3 | NIC | unconnected | Not internally connected; this pin is not connected internally. |
| 4 | GND | power_in | Ground reference for the voltage reference. |
| 5 | TRIM | passive | Output voltage trim; a potentiometer wiper connected here adjusts VOUT over a ±0.5% range without compromising performance. |
| 6 | VOUT | power_out | Reference output that sources up to 10 mA and sinks up to −5 mA, and requires a 0.1 µF output capacitor for stability. |
| 7 | NIC | unconnected | Not internally connected; this pin is not connected internally. |
| 8 | DNC | unconnected | Do not connect; the datasheet says do not connect to this pin. |
