AZ4558AM

Advanced Analog Circuits Data Sheet AZ4558A DUAL LOW NOISE OPERATIONAL AMPLIFIERS General Description The AZ4558A consists of two low noise, high performance operational amplifiers. It is specially suitable for applications in differential-in, differential-out as well as in industrial measurement tools and applications where gain and phase matched channels are mandatory. The IC features monolithic silicon chip, internal frequency compensation, low noise, low distortion, wide operating voltage range, high gain and high bandwidth. The AZ4558A can operate under dual power supply voltage up to ±18V or single power supply up to 36V.
