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.
