HA5025

September 1998

File Number 3591.4

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.
