RC4739 Replacement Ic

Description

This is my version of a replacement Ic of the RC4739.

After checking many new and faster op amps, I’ve found out that they can be noisier or unstable (due to the wider bandwidth) in some applications.

I’ve decided to use the 4558 op amp – that present equal or better specs, and works perfectly as a replacement for the RC4739.
