LM4558
The LM4558 is a dual operational amplifier integrated circuit designed for audio and general-purpose analog signal processing. It was originally produced by National Semiconductor and is now offered under Texas Instruments after the two companies’ semiconductor assets merged. The device houses two identical op-amps in a single 8-pin package and is commonly available in DIP-8 and SO-8 forms.
The standard pinout corresponds to a typical dual op-amp arrangement: each amplifier has an inverting and a
The LM4558 is known for low-noise performance and good fidelity, attributes that have made it popular in
