HA5024
September 1998
File Number 3550.4
Quad 125MHz Video Current
Feedback Amplifier with Disable
The HA5024 is a quad version of the popular Intersil
HA5020. It features wide bandwidth and high slew rate, and
is optimized for video applications and gains between 1 and
10. It is a current feedback amplifier and thus yields less
bandwidth degradation at high closed loop gains than
voltage feedback amplifiers.
The low differential gain and phase, 0.1dB gain flatness, and
ability to drive two back terminated 75Ω cables, make this
amplifier ideal for demanding video applications.
The HA5024 also features a disable function that
significantly reduces supply current while forcing the output
to a true high impedance state. This functionality allows 2:1
and 4:1 video multiplexers to be implemented with a single IC.
The current feedback design allows the user to take
advantage of the amplifier’s bandwidth dependency on the
feedback resistor. By reducing RF, the bandwidth can be
increased to compensate for decreases at higher closed
loop gains or heavy output loads.
