General Description  
AZ4558  
Features  
The AZ4558 consists of two high performance opera-  
tional amplifiers. The IC features high gain, high input  
resistance, excellent channel separation, wide range of  
operating voltage and internal frequency compensa-  
tion. It is specifically suitable for applications in differ-  
ential-in, differential-out as well as in potential-metric  
amplifiers and where gain and phase matched channels  
are mandatory. The AZ4558 contains ± 18Vmaximum  
power supply voltage.
