ADR440ARMZ-REEL7
Analog Devices · Voltage Reference · MSOP-8
ADR440ARMZ-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; no circuit should be connected to this pin. |
| 2 | VIN | power_in | Input voltage connection, specified for 3 V to 18 V with at least 500 mV headroom above VOUT. |
| 3 | NIC | unconnected | Internally not connected; these pins are not internally interconnected to the rest of the device. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM | passive | Output voltage trim pin; a potentiometer between VOUT and GND with its wiper here trims the output within 0.5% without affecting performance, and all trim resistors must be low-temperature-coefficient types. |
| 6 | VOUT | power_out | Output voltage; sources up to 10 mA and sinks up to -5 mA, with output short-circuit current of 27 mA. |
| 7 | NIC | unconnected | Internally not connected; these pins are not internally interconnected to the rest of the device. |
| 8 | DNC | unconnected | Do not connect; no circuit should be connected to this pin. |
