ADR1581ARTZ-REEL7
Analog Devices · Voltage References · SOT-23
ADR1581ARTZ-REEL7 from Analog Devices, in a SOT-23. 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 | V+ | power_in | Positive terminal of the 2-terminal shunt reference, where the reverse current flows in from the external series resistor RS over the stated 60 μA to 10 mA operating range. |
| 2 | V- | power_in | Negative (common) terminal of the shunt reference, with the 1.250 V reference voltage appearing between V+ and V-. |
| 3 | NC | unconnected | No connect pin in the SOT-23 pin configuration; the figure notes it may alternatively be tied to V-. |
