General Description
The NJM4558 is a dual voltage feedback amplifier that is internally frequency
compensated to provide unity gain stability. The NJM4558 offers 3.5MHz of
bandwidth at a gain of 2. The NJM4558 also features high gain, low input
voltage noise, high input resistance, and superb channel separation making
it well suited for audio filter applications in set-top-boxes, DVD players, and
televisions.
The NJM4558 is designed to operate over a wide power supply voltage range,
±2V to ±18V (4V to 36V). It utilizes an industry standard dual amplifier pin-
out and is available in a Pb-free, RoHS compliant SOIC-8 package.
