Operational Amplifier. GS4558 Datasheet
Dual Wide Bandwidth Operational Amplifier
The GS4558 device is dual general-purpose
operational amplifier with each half electrically
similar to the µA741 except that offset null
capability is not provided.
The high common-mode input voltage range and
the absence of latch-up make this amplifier ideal
for voltage-follower applications. The device is
short-circuit protected and the internal frequency
compensation ensures stability without external
The GS4558 is characterized for operation from
0°C to 70°C.

Stresses above those listed under «Absolute Maximum Ratings» may cause permanent damage to the
device. These are stress ratings only and functional operation of the device at these or any other
conditions above those indicated in the operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.
Note 1: All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and
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
15V, whichever is less.
Note 4: Temperature and/or supply voltages must be limited to ensure that the dissipation rating is not
