AiP4558SSA8.TB

Wuxi I core Elec · Operational Amplifier · SOP-8

AiP4558SSA8.TB from Wuxi I core Elec, 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 1OUT output Output of channel 1 of the dual op-amp.
2 1IN- input Inverting input of channel 1.
3 1IN+ input Non-inverting input of channel 1.
4 VCC- power_in Negative power supply; the datasheet gives the supply range as 3 V to 36 V (VCC+ minus VCC-), with the common-mode input range from 0 V to VCC-2 V.
5 2IN+ input Non-inverting input of channel 2.
6 2IN- input Inverting input of channel 2.
7 2OUT output Output of channel 2 of the dual op-amp.
8 VCC+ power_in Positive power supply; the datasheet gives the supply range as 3 V to 36 V, and the absolute maximum supply voltage as 40 V or ±20 V.
