AZ4580
DUAL LOW NOISE OPERATIONAL AMPLIFIERS
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
鹵18V
or single
power supply up to 36V.
