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

ADR02WARZ-REEL 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 | NIC | unconnected | No internal connect. |
| 2 | VIN | power_in | Supply input; the ADR02 operates from 7.0 V to 36.0 V. |
| 3 | TEMP | output | Temperature-sensing output that can be used with an external buffer and a simple resistor network for temperature sensing and approximation. |
| 4 | GND | power_in | Ground. |
| 5 | TRIM | input | Trim pin for fine adjustment of the output voltage. |
| 6 | VOUT | power_out | Reference output of 5.0 V for the ADR02, with output current up to 10 mA. |
| 7 | NIC | unconnected | No internal connect. |
| 8 | NIC | unconnected | No internal connect. |
