AD8641AKSZ-REEL7

Tokmas · Precision Op Amps · SOT-23-5L

AD8641AKSZ-REEL7 from Tokmas, in a SOT-23-5L. 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.
2 -VS power_in Negative power supply, normally tied to ground; it may be tied to another voltage as long as the voltage between VS+ and VS- is 4.5 V to 48 V.
3 +IN input Non-inverting amplifier input with a common-mode voltage range from VS- to VS+ - 1.5 V.
4 -IN input Inverting amplifier input with a voltage range from VS- to VS+ - 1.5 V.
5 +VS power_in Positive power supply, 4.5 V to 48 V (split supplies allowed as long as VS+ to VS- is 4.5 V to 48 V).
