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.

Description

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. HA5024 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 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 amplifiers bandwidth dependency on the feedback resistor. By reducing RF, the bandwidth can be increased to compensate for decreases at higher closed loop gains or heavy output loads.
