Description
The RC4559 integrated circuit is a high performance dual
operational amplifier internally compensated and con-
structed on a single silicon chip using an advanced epitaxial
process.
These amplifiers feature improved AC performance which
far exceeds that of the 741-type amplifiers. The specially
designed low-noise input transistors allow the RC4559 to be
used in low-noise signal processing applications such as
audio preamplifiers and signal conditioners.
The RC4559 also has more output drive capability than
741-type amplifiers and can be used to drive a 600
W
load.
