AD8628ARZ from UMW, in a SOP-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 | NC | unconnected | Marked NC in the SOP-8 pin configuration, so no electrical function is assigned to this pin. |
| 2 | -IN | input | Inverting input; the common-mode input range is 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, and series resistors should limit input current to less than 5 mA if the input can exceed a supply rail. |
| 3 | +IN | input | Non-inverting input; the common-mode input range is 0 V to 5 V at VS = 5 V and 0 V to 2.7 V at VS = 2.7 V, and series resistors should limit input current to less than 5 mA if the input can exceed a supply rail. |
| 4 | V- | power_in | Negative supply rail; the part is specified for 2.7 V to 5 V single-supply or ±1.35 V to ±2.5 V dual-supply operation. |
| 5 | NC | unconnected | Marked NC in the SOP-8 pin configuration, so no electrical function is assigned to this pin. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing; output current is specified at ±30 mA (typical) at VS = 5 V. |
| 7 | V+ | power_in | Positive supply rail; the device is fully specified from 2.7 V to 5 V single supply, with PSRR specified for VS = 2.7 V to 5.5 V. |
| 8 | NC | unconnected | Marked NC in the SOP-8 pin configuration, so no electrical function is assigned to this pin. |
