Key parametric limits for BOM fit
The BA4558RF-E2: Input offset voltage is 500 µV, input bias current 60 nA. Quiescent supply current is 3 mA for both amplifiers, which keeps the power budget modest in multi-rail designs.

Frequently asked questions
Is BA4558RF- obsolete or end-of-life?
No — BA4558RF- carries an active product status.
Does BA4558RF- have a direct replacement or equivalent?
The closest functional peer is the BA4558YF-MGE2, which shares the same 2 MHz GBW, 1 V/µs slew rate, and 60 nA input bias current, but adds AEC-Q100 automotive qualification and a different package variant. For a non-automotive BOM, the BA4558RF- is the standard industrial-grade choice.
