Analog Devices · Voltage References · SOIC-8
ADR434BRZ 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; the datasheet gives the ADR434 operating supply range as 6.1 V to 18 V. |
| 3 | NIC | unconnected | Not Internally Connected; this pin is not connected internally. |
| 4 | GND | power_in | Ground reference pin for the reference. |
| 5 | TRIM | passive | Output voltage trim terminal used to adjust VOUT; the applications section states the adjustment range as ±0.5%. |
| 6 | VOUT | power_out | Reference output voltage; the ADR434 nominal output is 4.096 V. |
| 7 | COMP | passive | Compensation input; connect a series resistor and capacitor network from COMP to VOUT to reduce overall noise. |
| 8 | DNC | unconnected | Do Not Connect; do not connect anything to this pin. |
