www.fairchildsemi.com 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 operational 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.
