ADR445ARZ-REEL7
Analog Devices · Voltage Reference · SOIC-8
ADR445ARZ-REEL7 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 | DNC | unconnected | Do not connect; do not connect anything to this pin. |
| 2 | VIN | power_in | Input voltage connection; for the ADR445 the operating range is 5.5 V to 18 V and VIN must be at least VOUT + 500 mV for regulation. |
| 3 | NIC | unconnected | Not internally connected; the pin is not connected internally. |
| 4 | GND | power_in | Ground reference for the reference output. |
| 5 | TRIM | passive | Output voltage trim; adjusts VOUT over a limited range of about ±0.5% through an external potentiometer, which must use low-temperature-coefficient resistors. |
| 6 | VOUT | power_out | Reference output voltage; sources up to 10 mA and sinks up to −5 mA. |
| 7 | NIC | unconnected | Not internally connected; the pin is not connected internally. |
| 8 | DNC | unconnected | Do not connect; do not connect anything to this pin. |
