Dual op-amp for audio and signal conditioning — 3 MHz GBP, AEC-Q100
Package, footprint, and supply-rail reality
The RC4558PS is supplied in an 8-SOIC package with a 5.30 mm body width, supplier device package code 8-SO. The mounting is surface-mount, and the shipping medium is Bulk. Input bias current is 150 nA typical, input offset voltage is 500 µV — both figures are adequate for DC-coupled audio and sensor conditioning but not for precision microvolt-level measurement. The differential output type means the part is intended for single-ended or differential signal paths; it is not a rail-to-rail output, so the output swing will not reach the supply rails. Design the common-mode range and output headroom accordingly.
