Dual Channel Operational Amplifiers
General Description
The
EC4558
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
EC4558
contains
18Vmaximum
power supply voltage.
The
EC4558
is available in DIP-8 or SOIC-8 package.
