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.
