Quad 125MHz Video Current Feedback Amplifier with Disable
The HA5024 is a quad 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 differentialgainandphase,0.1dBgainflatness, and ability to drive two back terminated 75cables, make this amplifier ideal for demanding video applications.
The HA5024 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 and 4:1 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 feedback resistor. By reducing R
, the bandwidth can be
F
increased to compensate for decreases at higher closed loop gains or heavy output loads.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe 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 tomaintain junction temperature below 175oC for die, and below 150oC for plastic packages. See Application Information section for safe operating area information.
2. θJA 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.

NOTES:
5. VCM = ±2.5V. At -40oC Product is tested at VCM = ±2.25V because short test duration does not allow self heating.
6. RL= 100,VIN= 2.5V. This is the minimum current which must bepulled out of the Disable pin in order to disable the output. The output is considered disabled when -10mV V
