RC4558
Dual High-Gain Operational Amplifier
Features
• 2.5 MHz unity gain bandwidth
• Supply voltage ±22V for RM4558 and ±18V for
RC/RV4558
• Short-circuit protection
• No frequency compensation required
• No latch-up
• Large common-mode and differential voltage ranges
• Low power consumption
• Parameter tracking over temperature range
• Gain and phase match between amplifiers
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.
