HA5023

Dual 125MHz Video Current

Feedback Amplifier

The HA5023 is a wide bandwidth high slew rate dual

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 75

Ω 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

increased to compensate for decreases at higher closed

loop gains or heavy output loads.

The performance of the HA5023 is very similar to the

popular Intersil HA-5020
