Data Sheet May 1999 File Number

Dual, 125MHz, Video Current Feedback
Amplifier with Disable

The HA5022 is a dual versionofthepopularIntersilHA5020.
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 75Ω 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
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 to maintain junction temperature below 175oC for die, and below150oC
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= 100Ω,VIN= 2.5V. This is the minimum current which must be pulled out of the Disable pin in order to disable the output. The output is
considered disabled when -10mV ≤ V

OUT

≤ +10mV.

7. VIN= 0V. This is the maximum current that can be pulled out of the Disable pin with the HA5022 remaining enabled. The HA5022 is
considered disabled when the supply current has decreased by at least 0.5mA.
