AD1580BKSZ-REEL7 from Analog Devices, in a SC-70-3. 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 | Negative terminal of the 2-terminal shunt reference (Figure 2, SC70 top view), which returns the reverse current; reverse current is specified from 50 µA to 10 mA. |
| 2 | V+ | power_in | Positive terminal of the 2-terminal shunt reference (Figure 2, SC70 top view), where the external series resistor RS sets the reverse current IR. |
| 3 | NC (OR V-) | unconnected | No-connect pin on the SC70 package per the pin configuration note (NC = NO CONNECT); the datasheet states it may alternatively be tied to V-. |
