The RC4559 is a dual high-performance operational amplifier. The high common-mode input voltage and the
absence of latch-up make this amplifier ideal for low-noise signal applications such as audio preamplifiers and
signal conditioners. This amplifier features a guaranteed dynamic performance and output drive capability that
far exceeds that of the general-purpose type amplifiers. Max power supply +/-36v. These work great in Klon clones. They are NOS and have been kept in antistatic sleeves.
