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
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 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
.

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175
o
C for die, and below 150
o
C
for plastic packages. See Application Information section for safe operating area information.
2.
JA
is measured with the component mounted on an evaluation PC board in free air.
3. The non-inverting input of unused amplifiers must be connected to GND.
4. Output is protected for short circuits to ground. Brief short circuits to ground will not degrade reliability, however, continuous (100% duty cycle)
output current should not exceed 15mA for maximum reliability.
