Data Sheet
DUAL OPERATIONAL AMPLIFIERS
General Description
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 can work with
±18V
maximum power supply
voltage.
The AZ4558 is specifically suitable for applications in
differential-in, differential-out as well as in potential-
metric amplifiers and where gain and phase matched
channels are mandatory.
The AZ4558 is available in DIP-8 and SOIC-8 pack-
age.
