ADR03BRZ

Analog Devices · Voltage References · SOIC-8

ADR03BRZ 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 Input supply; the ADR03 operates from 4.5 V to 36.0 V.
3 TEMP output Temperature-sensing output that, with an external buffer and a simple resistor network, can be used for temperature sensing and approximation.
4 GND power_in Ground.
5 TRIM input Trim pin provided for fine adjustment of the output voltage.
6 VOUT output Reference output, 2.5 V for the ADR03, with up to 10 mA output current.
7 NIC unconnected No internal connect.
8 NIC unconnected No internal connect.
