HA5023
September 1998
File Number 3393.6
Dual 125MHz Video Current
Feedback Ampli鏗乪r
The HA5023 is a wide bandwidth high slew rate dual
ampli鏗乪r 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 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.
The performance of the HA5023 is very similar to the
popular Intersil HA-5020
