General Description
The AZ4580 is a dual low noise operational amplifier.
It is specifically designed for audio systems to improve
tone control; it can also be used in pre-amplifier, indus-
trial measurement tools and applications where gain
and phase matched channels are mandatory.
The IC features monolithic silicon chip, internal fre-
quency compensation, low noise, low distortion, high
gain and high bandwidth. The AZ4580 can operate
under dual power supply voltage up to
18V or single
power supply up to 36V.
Features

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 Operation Ratings" is not implied. Exposure to "Absolute Maximum Rat-
ings" for extended periods may affect device reliability.
