MIK4558
Dual Wide Bandwidth
Operational Amplifier
November 2001
Description
The MIK4558 devices are dual general-purpose operational amplifiers with each half electrically similar to the
A741 except that offset
null capability is not provided. The high common-mode input voltage range and the absence of latch-up make these amplifiers ideal for
voltage-follower applications. The devices are short-circuit protected and the internal frequency compensation ensures stability without
external components. The MIK4558 is characterized for operation from 0C to 70C.

Note 2: Differential voltages are at IN+ with respect to IN .
Note 3: The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
Note 4: Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not exceeded.
