HA5022

Dual, 125MHz, Video Current Feedback

Amplifier with Disable

The HA5022 is a dual version of the popular Intersil HA5020.

It features wide bandwidth and high slew rate, and is

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 HA5022 also features a disable function that

significantly reduces supply current while forcing the output

to a true high impedance state. This functionality allows 2:1

video multiplexers to be implemented with a single IC.

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.
