Quad, 125MHz Video
Current Feedback Amplifier
The HA5025 is a wide bandwidth high slew rate quad
amplifier 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 current feedback design allows the user to take
advantage of the amplifier’s bandwidth dependency on the
feedback resistor.
The performance of the HA5025 is very similar to the
popular Intersil HA-5020.
