DUAL LOW NOISE OPERATIONAL AMPLIFIERS AZ4580

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 pre­amplifier, industrial measurement tools and applica­tions where gain and phase matched channels are man­datory.

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 and
TSSOP-8 packages.
