# ADR02BRZ

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

ADR02BRZ 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; the pin is not connected inside the device. |
| 2 | VIN | power_in | Supply input; ADR02 operating range is 7.0 V to 36.0 V with an absolute maximum supply voltage of 36.0 V. |
| 3 | TEMP | output | Temperature-proportional output of about 550 mV at 25°C with 1.96 mV/°C sensitivity; it must be buffered because current drawn from it disturbs VOUT. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM | input | Output voltage trim terminal; with the optional trim network the ADR02 output adjusts from 4.95 V to 5.02 V. |
| 6 | VOUT | power_out | 5.0 V reference output, high output current of 10 mA, short-circuit current 30 mA typical to GND. |
| 7 | NIC | unconnected | No internal connect; the pin is not connected inside the device. |
| 8 | NIC | unconnected | No internal connect; the pin is not connected inside the device. |
