DUAL OPERATIONAL AMPLIFIERS
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 can work with
±18V
maximum power supply
voltage.
The AZ4558 is specifically suitable for applications in
differential-in, differential-out as well as in potential-
metric amplifiers and where gain and phase matched
channels are mandatory.
The AZ4558 is available in DIP-8 and SOIC-8 pack-
age.

Note 1: 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 Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods may affect device reliability.
