Description

The RC4559 is a dual high-performance operational amplifier. The high common-mode input voltage and the absence of latch-up make this amplifier suitable for low-noise signal applications such as audio preamplifiers and signal conditioners. This amplifier features a dynamic performance that is specified by design and an output drive capability that far exceeds general-purpose type amplifiers.

The RC4559 is characterized for operation from 0°C to 70°C.
