AD8641AKSZ-R2 from Analog Devices, in a SC-70-5. 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 | OUT | output | Amplifier output with a rail-to-rail output stage, rated for ±6 mA output current at VS = 5 V (Table 1), and stable with capacitive loads of more than 500 pF. |
| 2 | VEE | power_in | Negative supply pin (V−); the datasheet specifies single-supply operation from 5 V to 26 V or dual-supply operation from ±2.5 V to ±13 V, with a supply absolute maximum of 27.3 V. |
| 3 | +IN | input | Non-inverting input with an input voltage range of 0 V to 3 V at VS = 5 V (Table 1) and an input bias current of 1 pA max at 25°C. |
| 4 | -IN | input | Inverting input sharing the same input characteristics as +IN, with an input bias current of 1 pA max at 25°C (Table 1). |
| 5 | VCC | power_in | Positive supply pin (V+); the datasheet specifies single-supply operation from 5 V to 26 V, with a supply absolute maximum of 27.3 V. |
