UA4558 amplifier equivalent, dual operational amplifier.
such as audio preamplifiers and signal conditioners. They are constructed using the Fairchild Planar* Epitaxial process..
- The J.lA4558 Monolithic Dual Operational Amplifiers consist of two independent high gain. internally frequency compensated operational amplifiers. The specially designed low noise input transistors allow the J.lA4558 to be used in low noise signal .
