September 1998 File Number 3591.4

Quad, 125MHz Video Current Feedback Ampliﬁer

The HA5025 is a wide bandwidth high slew rate quad ampliﬁer optimized forvideoapplicationsandgainsbetween 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, 0.1dB gain ﬂatness, and ability to drive two back terminated 75Ω 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.

The performance of the HA5025 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 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 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.
