Quad, 125MHz Video
Current Feedback Ampliï¬er
The HA5025 is a wide bandwidth high slew rate quad
ampliï¬er optimized for video applications and gains between
1 and 10. It is a current feedback ampliï¬er and thus yields
less bandwidth degradation at high closed loop gains than
voltage feedback ampliï¬ers.
The low differential gain and phase, 0.1dB gain ï¬atness, and
ability to drive two back terminated 75⦠cables, make this
ampliï¬er ideal for demanding video applications.
The current feedback design allows the user to take
advantage of the ampliï¬erâs bandwidth dependency on the
feedback resistor.
The performance of the HA5025 is very similar to the
popular Intersil HA-5020.
