TECHNICAL DATA
DUAL OPERATIONAL AMPLIFIER IL4580
GENERAL DESCRIPTION
The IL4580 is the dual operational amplifier, specially designer for
improving the tone control, which is most suitable for the audio application.
ORDERING INFORMATION
IL4580N Plastic
IL4580D SOIC
TA = -40° to 85° C
for all packages.
Featuring noiseless, higher gain bandwidth, high output current and low
distortion ratio, and it is most suitable not only for acoustic electronic parts of
audio pre-amp and active filter, but also for the industrial measurement tools.
It is also suitable for the head phone amp at higher output current, and further
more, it can be applied for the handy type set operational amplifier of general
purpose in application of low voltage single supply type which is properly
biased of the input low voltage source.
FEATURES
• Operating Voltage (±2 V ∼ ±18 V)
• Wide Gain Bandwidth Product (15 MHz typ.)
• Slew Rate (5 V/µs typ.)
• Bipolar Technology
