Analog Devices · FET InputAmplifiers · SC-70-5

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.
