Dual, 125MHz, Video Current Feedback
Ampli鏗乪r 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 ampli鏗乪r and thus yields less
bandwidth degradation at high closed loop gains than
voltage feedback ampli鏗乪rs.
The low differential gain and phase, 0.1dB gain 鏗俛tness, and
ability to drive two back terminated 75鈩?cables, make this
ampli鏗乪r ideal for demanding video applications.
The HA5022 also features a disable function that
signi鏗乧antly 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 ampli鏗乪r鈥檚 bandwidth dependency on the
feedback resistor. By reducing R
F
, the bandwidth can be
increased to compensate for decreases at higher closed
loop gains or heavy output loads.
