General Description
The AV4558 is dual general purpose operational amplifiers.
The high common-mode input voltage range and the absence
of latch-up make these amplifiers ideal for voltage follower
application.
The devices are short circuit protected and the internal freq-
uency compensation ensures stability without external compo-
nents.
Features
Maximum supply voltage : 18V
Large DC Voltage Gain : 100dB
Bandwidth (unity gain) : 1 MHz
Short-Circuit Protection
Wide common-mode and differential ranges
No frequency compensation required
Low power consumption
No latch-up
Gain and phase math between amplifiers

Applications
Amplifiers
Filters
Analog Circuit

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range
GND
(V
IN
or V
OUT
)
V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
).
Unused outputs must be left open.
