DUAL LOW NOISE OPERATIONAL AMPLIFIERS
General Description
The AZ4580 is a monolithic dual low noise operational
amplifier. It is specifically designed for audio systems
to improve tone control; it can also be used in pre-
amplifier, industrial measurement tools and applica-
tions where gain and phase matched channels are man-
datory.
The IC features internal frequency 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.
The AZ4580 is available in DIP-8, SOIC-8, SIP-8 and
TSSOP-8 packages.

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 indi-
cated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended
periods may affect device reliability.
