General Description
The AZ4558 consists of two high performance opera-
tional amplifiers. The IC features high gain, high input
resistance, excellent channel separation, wide range of
operating voltage and internal frequency compensa-
tion. It is specifically suitable for applications in differ-
ential-in, differential-out as well as in potential-metric
amplifiers and where gain and phase matched channels
are mandatory. The AZ4558 contains
±
18Vmaximum
power supply voltage.
The AZ4558 is available in DIP-8 or SOIC-8 package.

Note: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated under "Recommended Operation Ratings" is not implied. Exposure to "Absolute Maximum Rat-
ings" for extended periods may affect device reliability.
