HA5023

HA5023 September 1998 File Number 3393.6 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 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. By reducing RF, the bandwidth can be 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.
