Description
The RC4558 integrated circuit is a dual high-gain opera-
tional amplifier internally compensated and constructed on a
single silicon IC using an advanced epitaxial process.
Combining the features of the 741 with the close parameter
matching and tracking of a dual device on a monolithic chip
results in unique performance characteristics. Excellent
channel separation allows the use of this dual device in dense
single 741 operational amplifier applications. It is especially
well suited for applications in differential-in, differential-out
as well as in potentiometric amplifiers and where gain and
phase matched channels are mandatory.
No latch-up
Large common-mode and differential voltage ranges
Low power consumption
Parameter tracking over temperature range
Gain and phase match between amplifiers
