# ADR435ARMZ

**Analog Devices** · Voltage References · MSOP-8

ADR435ARMZ 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; do not connect to this pin. |
| 2 | VIN | power_in | Input voltage connection; ADR435 operating range 7.0 V to 18 V (absolute maximum supply 20 V). |
| 3 | NIC | unconnected | Not Internally Connected; this pin is not connected internally. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM | passive | Output voltage trim terminal that adjusts the output over a ±0.5% range. |
| 6 | VOUT | power_out | Output voltage (5.000 V for ADR435), sourcing up to 30 mA and sinking up to -20 mA. |
| 7 | COMP | passive | Compensation input; connect a series resistor and capacitor network from COMP to VOUT to reduce overall noise, and leave unconnected if unused. |
| 8 | DNC | unconnected | Do Not Connect; do not connect to this pin. |
