AD8628ARZ-REEL7 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 | NC | unconnected | No-connect pin, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier. |
| 2 | -IN | input | Inverting input of the amplifier; the common-mode input range is 0 V to 5 V with VS = 5 V (Table 1). |
| 3 | +IN | input | Non-inverting input of the amplifier; the common-mode input range is 0 V to 5 V with VS = 5 V (Table 1). |
| 4 | V- | power_in | Negative supply rail; the part operates from 2.7 V to 5 V single supply, or ±1.35 V to ±2.5 V dual supply. |
| 5 | NC | unconnected | No-connect pin, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing; short-circuit limit is ±25 mA typical and output current is ±30 mA at 25 °C (Table 1). |
| 7 | V+ | power_in | Positive supply rail; the part operates from 2.7 V to 5 V single supply, or ±1.35 V to ±2.5 V dual supply. |
| 8 | NC | unconnected | No-connect pin, marked NC in Figure 2 of the datasheet, so it is not used by the amplifier. |
